Henry Huiyao Wang: A New Compact for China and Europe

CCG President outlines opportunities for China and Europe to deepen cooperation in trade, investment, climate action, and global governance.

[from the Center for China & Globalization, 7 November 2026]

Henry Huiyao Wang [王辉耀], Founder and President of the Center for China & Globalization (CCG), has published an article titled “A New Compact for China and Europe” in the Autumn 2026 issue (No. 36) of Horizons, a journal published by the Center for International Relations and Sustainable Development (CIRSD).

China and Europe possess almost everything needed for a consequential partnership. Their economies are deeply intertwined. They have no fundamental geopolitical disputes. And they share important interests in climate action, global development, and a functioning multilateral system. Yet the bilateral relationship is weaker than it could be. At its core is a commercial dispute over trade, which is turning what should be a fruitful relationship built on shared interests into one increasingly characterized by the language of industrial vulnerability and tariffs.

Trade has thus become a wedge issue that risks souring a mutually beneficial interdependence. And it comes at a poor moment. The international order is moving away from the unipolar era that followed the Cold War and into a new multipolar era, one in which multilateralism, and the defense of our shared global institutions, matter more than ever. Wars, tariff conflicts, technological fragmentation, and pressure on multilateral institutions are producing a world that is more multipolar but no more governable. Now more than ever, we need cooperation on global governance across a wide range of transnational issues, from climate change to artificial intelligence.

Europe in a Multipolar World

For much of the postwar period, the transatlantic alliance provided the central structure of European security. But the era of American hegemony, when diplomatic sleepwalking was permissible, is over. It seems clear that European policymakers have long since realized that formal alliances and shared values are no longer a substitute for independent judgment on geopolitical and economic questions, at a time when American policy is nakedly unilateral, transactional, and protectionist—and thus hostile to European interests.

Unwilling to be a passive participant in American power politics, or to be caught between the United States and China, Europe has already begun charting a course toward strategic autonomy, even if its exact shape is not yet settled. China, for its part, understands that asking Europe to “choose China” over the United States is not a palatable proposition—least of all now, when self-determination and strategic autonomy have become a clear European focus.

Instead, from China’s perspective, a break from “the West versus the rest” is victory enough, because it enables a shift away from alignment based on ideology toward a world of tactical cooperation based on the merits of each issue.

Canadian Prime Minister Mark Carney offered a useful description of this at Davos this year, calling for “variable geometry”: different coalitions for different issues, built around shared interests rather than around values that are not firmly or equally upheld. In this framing, Europe can cooperate as closely as it wishes with the United States on defense, while still finding common cause with China on climate and trade reform, or with India on development. Such flexibility is increasingly the default in our plural world.

A cohesive Europe able to act independently is preferable to a divided continent whose China policy is increasingly shaped elsewhere. But that also means that policymakers in China must address European fears if they are to benefit from engagement and cooperation on shared interests.

The Changing Bargain

The core anxiety facing Europe, and the one undermining a merits-based relationship, is that the old, unspoken economic bargain—European technology and premium manufacturing in exchange for Chinese consumer goods and lower-cost production—is giving way to a more competitive relationship.

China now possesses broad industrial ecosystems, world-class infrastructure, skilled engineering talent, and the capacity for fast commercialization at scale. It no longer competes on wages alone. In electric vehicles, batteries, solar energy, machinery, telecommunications equipment, and, increasingly, advanced digital applications, Chinese firms can combine cost, speed, and technological capability.

But let us not get carried away with catastrophizing. The shared economic foundation between China and the EU remains immense. In 2025, two-way trade in goods and services exceeded €880 billion. Europe imported more than €570 billion in goods from China and exported about €200 billion, producing a large bilateral goods deficit. Yet this figure should be interpreted carefully. The European Union still recorded an overall goods surplus of approximately €128 billion in 2025, as well as a substantial current-account surplus. Nor are all imports finished products: Eurostat data shows that 57 percent of all extra-EU goods imports in 2025 were intermediate products, meaning that much of what Europe imports feeds into value-added production chains from which Europe itself benefits. Europe’s difficulty is that, while its industry remains broadly profitable, certain critical sectors are already under pressure, and the trend seems unlikely to reverse suddenly in favor of European manufacturing.

Europe is not facing this crisis in a vacuum, either. It is compounded by high energy costs, aging populations, fragmented capital markets, and chronic underinvestment. The result is a genuine fear of deindustrialization, with the attendant loss of skilled employment, supplier networks, technological capacity, and social cohesion. This worry is especially potent in the major European economies with large export-oriented manufacturing sectors, such as Germany, France, Italy, and Spain, and it makes the debate over “overcapacity” deeply politically charged.

While the imbalance is a product of industrial excellence, it can also be attributed to weak domestic demand in China. Household consumption there remains around 40 percent of GDP, while families save heavily out of concern over housing, education, health care, and retirement. The 2025 consumption action plan addressed wages, pensions, health care, childcare, paid leave, and benefits for migrant and flexible workers, and China’s first five-year plan devoted specifically to consumption subsequently set a goal of approximately 60 trillion yuan in retail sales by 2030. But it is far too early to call the effort complete. Although per capita disposable income rose by 5 percent and consumption expenditure by 4.4 percent in 2025, the first half of 2026 was weaker, and overall consumption still lags behind where it should be. Stronger pensions, health care, unemployment insurance, childcare, and portable benefits for migrant workers will help reduce precautionary saving, and greater access for foreign goods and services would ensure that stronger Chinese demand creates opportunities for European producers. That transformation, however, is not yet complete.

Europe, for its part, should recognize that competitive success is not in itself an unfair subsidy. The International Energy Agency estimates that producing a battery-electric vehicle costs more than 30 percent less in China than in advanced economies, with only about one-third of the gap attributable to the battery; a similar cost gap exists for conventional vehicles. China’s earlier industrial policies undoubtedly helped establish this ecosystem, but important forms of direct support, including national EV purchase subsidies, have already been phased out.

Rhodium Group estimates that BYD enjoys a cost advantage of approximately $4,700 per vehicle over Tesla’s operations in China, of which grants account for only about $292, while vertical integration and lower research, administrative, and supplier costs explain at least three-quarters of the difference. BYD produces roughly 70 percent of its components in-house, including its batteries. Europe should investigate market-distorting support and is right to insist on transparency, but it should not define the ecosystem, technology, and efficiencies China has built as unfair.

Nor is China’s automobile sector insulated from competition. The number of Chinese electric-vehicle makers was reported at 487 in 2018; by 2025, consolidation had reduced the market to approximately 129 brands produced by about 50 manufacturers, and only 10 to 15 are expected to be profitable by 2030. China exported approximately 5.86 million of the more than 31 million vehicles it sold in 2024, meaning that the large majority were still absorbed at home. By comparison, Volkswagen delivered 9.03 million vehicles worldwide but only 1.12 million in Germany, while Toyota and Lexus sold 10.16 million worldwide and 1.44 million in Japan. Airbus, likewise, sells approximately 68 percent of its aircraft outside Europe. Producing for global markets is accepted as normal when established European or Japanese companies do it; it should not automatically become illegitimate when Chinese firms do the same.

China’s textile industry offers a further precedent. Even as wages rose and some production moved to Vietnam, Bangladesh, and elsewhere, China retained 37 percent of global textile exports and 34 percent of clothing exports in 2017, because supplier clusters, infrastructure, skills, and continual upgrading proved more durable than low labor costs alone.

Beyond economic competition, clearer rules are urgently needed on the securitization of critical industries. The dispute over Nexperia—the Chinese-owned semiconductor company placed under Dutch government control in 2025—rattled supply chains and deepened concern in China about investing abroad. Either the company should not have been sold in the first place, or a clearer regulatory environment might have avoided a quasi-nationalization that rapidly internationalized a corporate dispute, and that still hangs over the mutual investment relationship today.

Likewise, proposals for a European instrument modeled on the United States’ Section 301 powers may offer political reassurance, but Section 301 is a blunt unilateral instrument designed to authorize retaliation. Europe would be better served by an explicitly transitional mechanism. Where an import surge threatens to destabilize domestic markets, temporary safeguards can provide time for adjustment, but they should be evidence-based, reviewable, and subject to firm sunset clauses. Their purpose should be to facilitate adaptation and negotiation, not to turn emergency protection into a permanent wall.

An Industrial Compact for Shared Competitiveness

When I visited Jean Monnet’s house outside Paris this summer, I was reminded of the method that helped build modern Europe: begin with concrete achievements that create the basis for solidarity. That method matters especially now, when trade has become a wedge issue and trust and trade cannot be separated.

We must therefore build a new industrial compact: one that aligns Chinese industrial capacity with Europe’s need for investment, innovation, and employment, and that enables China and Europe to stand together in support of a world of free, fair, and open trade.

First, China should follow through on its ongoing shift from an export– and investment-heavy model toward consumption-led growth. Alongside the social measures described above, this requires reducing the barriers faced by private and foreign businesses, improving market access in services and public procurement, and applying regulation more transparently. European companies should be able to compete in China with confidence that they will receive equal treatment and can protect their intellectual property.

Second, Europe needs to draw a sharper distinction between trade in products that present a genuine security risk and investment that strengthens European productive capacity. Concerns about supply-chain resilience and security in defined strategic sectors are unavoidable, given increasing regionalization. But a presumption against Chinese investment would deprive Europe of capital, technology, competition, and jobs precisely when it needs them most. Instead, Europe could openly welcome investment that meets its requirements on governance, data protection, labor standards, and environmental performance, while increasing the local economic contribution such production provides.

This openness should be anchored by a renewed Comprehensive Agreement on Investment. The agreement reached in principle in 2020 was never implemented and the relationship has changed too much for it simply to be revived unchanged. China and Europe should instead negotiate a new CAI covering market access, national treatment, subsidy transparency, technology transfer, public procurement, and enforceable dispute resolution. It should give European companies more predictable access to China, while establishing clear and consistent conditions for Chinese market access and investment in Europe, with an eye to creating employment and supplier networks there.

China has already demonstrated the value it places on market access by extending tariff-free treatment to goods from 53 African countries, and it could move explicitly to align its standards more closely with Europe’s. Europe, for its part, should reconsider its technology and investment restrictions—especially those implemented specifically to protect U.S. interests, such as the restrictions preventing China from purchasing advanced semiconductor equipment from ASML. Working examples of Chinese investment in Europe already exist. Chinese companies are investing in battery and vehicle production in Hungary, Slovakia, Spain, and Serbia, while European manufacturers—including Volkswagen, BMW, and Mercedes-Benz—continue to deepen their research, production, and partnership networks in China. These investments should not be viewed as isolated commercial transactions. They can become the architecture of a more balanced relationship.

Third, localization must mean more than final assembly. Joint ventures and investment agreements can encourage local supplier development, worker training, research partnerships, and the sharing of production know-how, while respecting intellectual-property rights. Chinese industry was once buoyed by European know-how through joint ventures; in return, European industry can now benefit from Chinese advances. The goal should be a competitive ecosystem in which both Chinese and European firms have a stake.

Fourth, any trade measures should be targeted and temporary. If an import surge threatens serious injury, safeguards can buy time for adaptation. But they should have clear evidentiary thresholds, sunset clauses, and review procedures. Protection without a productivity strategy merely postpones decline and risks marginalization, rather than allowing a dynamic industrial sector to emerge. At the same time, Europe can and should complete its own agenda: lowering energy costs, deepening the single market, mobilizing investment, scaling up innovative companies, and improving infrastructure.

Here, China can become Europe’s “fitness partner.” The phrase may sound counterintuitive at a moment of industrial anxiety, but the underlying idea is important. Healthy competition from China can push European companies and governments to confront long-delayed reforms, reduce costs, and innovate faster. Shelter from competitive pressure does not create health; competition, by contrast, can serve as a yardstick for rebuilding strength. China, meanwhile, gains more from a prosperous and capable Europe than from a weakened market increasingly hostile to Chinese commerce.

Finally, the compact should look beyond the bilateral market. Chinese and European joint ventures could look abroad, toward the product and development needs of the Global South. Joint production for Global South markets could be a starting point, moving in time toward joint financing of development and infrastructure to accelerate green industrialization in Africa, Asia, Latin America, and the Middle East.

This would represent the next stage of globalization: not simply Chinese companies “in China, for the world,” but “in the world, for the world.” It would spread productive capacity more widely, answer concerns about concentrated supply chains, and make development a shared undertaking rather than an arena for geopolitical competition.

From Commercial Trust to Strategic Cooperation

An industrial compact cannot by itself remove all political differences. But it would serve as a springboard, and a trust-building exercise, for deeper commitments and further work on shared interests.

Climate cooperation is the most obvious bridge. China’s manufacturing scale has lowered the global cost of solar panels, batteries, and electric vehicles, in a very real way underwriting the transition away from fossil fuels. At the same time, Europe is suffering under the weight of an energy crisis born of Russia’s invasion of Ukraine and, more recently, of upheavals in the Middle East around the Strait of Hormuz and the Bab al-Mandeb. A natural alignment would be for China and Europe to build a green partnership that helps wean the world off volatile fossil fuels and address the climate crisis. The exact shape of such measures is not yet defined, but using joint ventures, cooperation, and technology exchange to tap Chinese expertise and cost advantages could benefit both sides while buoying the global green transition. A tariff spiral in clean technology, by contrast, would make the energy transition slower and more expensive for everyone.

More broadly, China and Europe share an interest in conflict resolution. China has always been clear that sovereignty and territorial integrity apply universally, that nuclear escalation is unacceptable, and that a negotiated settlement must provide credible security for all parties. But it can do more to ease the concerns of a Europe that feels threatened by a Russia now in its fifth year of fighting in Ukraine. Working together, Europe and China could help provide an off-ramp, each using its leverage to bring the negotiating positions closer together. A truly durable settlement, acceptable to both sides, may eventually require security guarantees involving both European and non-European countries, and China could contribute through reconstruction, nuclear safety, and peacekeeping. The Middle East is another region where common interests are greater than current policy coordination suggests. Continued conflict and volatility around the straits have not only given fresh impetus to the transition away from fossil fuels but also created a new area of shared interest. Together, Europe and China could support a peace architecture with wider international participation.

Artificial intelligence governance is another opportunity. China and Europe approach data, platforms, and regulation differently, but both reject a future in which a handful of private companies set global rules without public accountability. They can work together on safety testing, scientific exchange, interoperable standards, and the application of AI to health, climate, and development. Agreement will be difficult, but building a shared environment for rule-making would help hedge against fragmentation in this rapidly developing field.

Finally, China and the EU have both long advocated restoring the World Trade Organization. A revitalized WTO already contains tools to address subsidies and demonstrable injury. Boeing and Airbus were both found, in WTO disputes, to have benefited from improper support, and those cases were handled through multilateral proceedings rather than through an open-ended campaign against either side’s wider industrial success. The WTO’s dispute-settlement system must now be restored, its rules on subsidies and state enterprises updated, and its development functions strengthened. The United States weakened that system by blocking appointments to the Appellate Body after adverse rulings; but China and Europe are both major beneficiaries of an open trading system, and both can press for reform.

None of this will be sustainable without renewed contact between societies. Direct flights, student exchanges, tourism, university partnerships, city-to-city links, and think-tank dialogue all have their roles to play, for they are the infrastructure of mutual understanding.

China–Europe relations will not always be perfectly aligned, and they will likely continue to contain elements of cooperation, competition, and disagreement. But together, we can put to rest the prospect of weaponized interdependence and move instead toward win-win interdependence.

Europe does not need to become less European in order to cooperate with China, nor does China need to adopt European political mores for cooperation to succeed. Both are now free to cooperate selectively and on the merits of each issue. And a world in which China and Europe cannot find areas of deep mutual interest—despite their deep economic ties and their shared stake in multilateralism—is a world that is measurably poorer for it.

Science-Watching: From Ignition to Energy

[from Science & Technology Review July/August 2025 Research Highlights, by Noah Pflueger-Peters]

Achieving ignition at the National Ignition Facility (NIF) proved that harnessing the power of the Sun in a laboratory may be possible. The Sun’s extreme temperatures and pressures cause light elements to fuse together to create heavier ones, releasing enormous energy and sustaining conditions for more thermonuclear reactions. NIF replicates these conditions with inertial confinement fusion, in which lasers compress and heat a target capsule filled with deuterium and tritium (DT), “heavy” isotopes of hydrogen that contain extra neutrons. When the isotopes fuse, they create helium and a neutron, and the lost mass is converted into inertial fusion energy (IFE), which can be harnessed for energy production.

Nuclear fusion produces significantly more energy than either nuclear fission or burning fossil fuels for equivalent amounts of fuel. Since the input materials for fusion energy are plentiful on Earth, an IFE power plant could produce safe, abundant, power grid-compatible energy without highly radioactive byproducts.

Although significant work remains to harness fusion energy, pursuing the development and deployment of IFE is crucial for the nation’s energy security, enabling the United States to shape implementation worldwide, avoid technological surprises from adversaries, and influence technical leadership in other energy-intensive technologies such as AI, machine learning (ML), and supercomputing.

IFE research stretches back to the early days of Lawrence Livermore, and today the Laboratory is fostering the overall fusion ecosystem. Livermore’s unique capabilities, expertise, and connections will be critical to laying the technical, logistical, and legal groundwork to make IFE possible. “IFE is a grand scientific and engineering challenge, something that is so incredibly difficult and high-risk and takes enormous expertise,” says Tammy Ma, Livermore’s IFE Institutional Initiative lead. “This challenge makes it the right kind of problem for national laboratories to pursue.”

Designing for Viability

NIF is the only facility to date to demonstrate the ignition and burning plasma conditions that are prerequisites for IFE, but it is an experimental facility for stockpile stewardship research, not a power plant. To be commercially viable and produce the energy to offset costs and meet demands (baseload power), IFE plants will need to generate more than 30 times the energy they deliver to the fusion target on every shot while firing 10 or more shots per second, compared to NIF’s rate of one or two shots per day.

The Laser Inertial Fusion Energy (LIFE) study, conducted between 2008 and 2013, aimed to build directly on technology developed for NIF to achieve IFE and took a systematic approach to this requirement by developing the Integrated Process Model (IPM). (See S&TR, April/May 2009 [archived PDF], pp. 6-15.)

IPM is a technoeconomic model of an IFE power plant with detailed technical and cost breakdowns and interdependencies of key systems and subsystems. “The work done under LIFE was fantastic,” says Ma. “IPM lays out engineering and physics requirements for the entire system to test out different scenarios and see the impact. Now, we not only get to expand on all that but also leverage 15 years of new data from NIF, better codes, and high-performance computing (HPC), as well as new work in AI, ML, advanced manufacturing, diagnostics, and nonproliferation across the Laboratory.”

IPM describes an IFE power plant that requires a solid-state laser driver system to “pump” lasers with optical energy using laser diodes instead of flashlamps as at NIF. The plant will also need to fabricate and fill target capsules onsite and send them into its target chamber at a high enough frequency to produce baseload power. “We will have to repeatedly inject targets into the chamber, so the targets must be able to withstand and survive that process,” explains Ma. “Then, the lasers will track the moving targets, and when one gets to the center of the chamber, they would fire on the centered target, repeating 10 to 20 times per second.”

The facility would convert fusion energy into heat and then electricity via steam turbines, sending most of the electricity to the power grid and recycling the rest to power operations on subsequent shots. Neutrons from the reaction would produce tritium needed for the DT fuel by bombarding lithium isotopes in a “breeding blanket” material lining its target chamber. By closing both the power and fuel cycles, IFE plants are expected to be self-sustaining.

Thanks in part to IFE STARFIRE (IFE Science and Technology Accelerated Research for Fusion Innovation and Reactor Engineering), a Department of Energy (DOE)-funded multi-institutional IFE research and development hub, researchers across the Laboratory are working to meet the new system’s demands. IPM can help identify key challenges, test the viability of new designs, and direct future research. “Many technical models and cost models exist for IFE, but very few, if any, pair systems and cost models together at the same depth as IPM,” says Mackenzie Nelson, a technoeconomic systems analyst in the Computational Engineering Division. “This type of tool offers such an advantage because we can assess design choices from both a technical and economic standpoint and create blueprints for what an IFE plant could look like.”

(left to right) Livermore researchers Bassem El Dasher, Claudio Santiago, and Mackenzie Nelson discuss a 3D model of a proposed IFE power plant design alongside the Integrated Process Model (IPM). IPM has more than 270 potential user inputs that researchers and collaborators can use to assess different IFE design choices to see the technical and cost impact on the entire design.

Operational Demands

NIF’s target capsules are extremely precise, fragile, and can take weeks to fabricate, fill, and position. Researchers are trying to reconcile that factor with the estimated demand of more than 800,000 capsules per day produced at less than $0.50 each to achieve IFE plant viability. To do this, they are examining optimal target designs for IFE and exploring advanced manufacturing methods such as microfluidics, volumetric additive manufacturing, and two-photon polymerization. (See S&TR, April/May 2025 [archived PDF], pp. 16-19.) Additional projects involve developing diagnostic instruments that can collect, analyze, and combine data with other diagnostics at the 10 to 20 shot per second frequency and use it to improve lasers in real time.

Fusion energy systems such as IFE are also a regulatory challenge, as they generate high-energy neutrons capable of breeding plutonium or uranium-233 and rely on large quantities of tritium. “Pure fusion energy systems do not require fissile material, but there are still ways to misuse these technologies that pose proliferation risk,” says Yana Feldman, the associate program leader for international safeguards. Bad actors may only need small amounts of tritium to make nuclear weapons, and some breeding blanket designs may inadvertently produce traces of plutonium that may be diverted for military purposes.

Nuclear fission reactors are regulated through international agreements and export control rules, and the independent International Atomic Energy Agency (IAEA) verifies that nuclear material and facilities are only being used for peaceful purposes. Neither treaties nor the IAEA address fusion energy, and no consensus has been reached on whether fusion energy systems need an international verification program. Verification methods for safeguarding tritium are also far less developed than for plutonium and uranium and focus more on contamination and transfers than analytical accounting for discrepancies. The precise scale of allowable tritium unaccounted for without posing proliferation risk is also unclear.

Fusion systems can be designed for proliferation resistance, but not having an existing design remains a challenge.

International security analyst Anne-Marie Riitsaar and her colleagues are exploring these complexities and starting conversations with international fusion experts and private industry to raise awareness. Riitsaar also plans to collaborate with the IPM team to map tritium diversion vulnerabilities and identify high-risk points where researchers could incorporate surveillance methods into plant designs to detect and prevent potential misuse. “People sometimes ask me why I’m thinking about fusion energy regulations and proliferation risks at this point, but it’s not too early,” says Riitsaar. “Reaching a multinational consensus on regulating sensitive technologies takes considerable time and effort.”

The National Ignition Facility is an experimental facility and not a power plant, so a commercial IFE plant design has vastly different requirements—many of which are being studied by Livermore researchers and their collaborators.

NIFViable IFE plant (estimated)
Repetition rateOne shot per day10 to 20 shots per second
Energy gain4.13 times (as of April 2025)30 times (minimum), 50 times to 100 times (ideal)

Laser alignmentComputationally in real time, taking up to 8 hoursIn real time
Power cycleOpen, requiring outside energy sourcesClosed, applying reused energy to power laser and ancillary plant operations
Fuel cycle (tritium)Produced offsiteBred onsite

The Laser Driven Fusion Integration Research and Science Test Facility (LD-FIRST) is a proposed blueprint for a proof-of-concept IFE facility that will test all the key IFE subsystems in an integrated fashion. A public-private partnership will likely be necessary to build the facility and will help the IFE community address the main subset of risks and the technological challenges of building a commercial plant.

Converging on a Solution

The team seeks to make IPM as accurate and comprehensive as possible by meeting with subject matter experts across the Laboratory to incorporate the latest research. “We’re trying to evolve the model so it has the same level of high detail across every single functional area to tell us where we can focus research and help us find optimized solutions that we could propose to industry,” says Nelson.

Computer scientist Claudio Santiago and his colleagues also modernized IPM by porting its framework from Microsoft Excel to Python in December 2024, making it compatible with AI, ML, design optimization, and HPC to further inform designs. “Once we think about all the forcing functions such as minimum shot yield and materials requirements pinning us in from every direction, we end up with an optimized solution space. As we sharpen the pencil more with these tools, that optimized solution box gets smaller until eventually we’ve converged on a point design,” says IFE lead systems engineer Justin Galbraith. Galbraith and his team’s point design is called the Laser Driven Fusion Integration Research and Science Test Facility, or LD-FIRST, a proof-of-concept physics demonstration facility for IFE. “That point design, we anticipate, will serve as the foundation for a future public-private partnership that would facilitate building and realizing a physical facility to focus the IFE community in pursuit of fusion power on the grid,” says Galbraith.

Livermore is leading the charge in IFE, helping the United States develop a technological roadmap, growing and coordinating science and technology efforts within the Laboratory, and fostering partnerships across the fusion industry, academia, and government.

Ma chaired DOE’s “Basic Research Needs for IFE” workshop and report in 2022 and co-chairs the subcommittee providing recommendations on the nation’s fusion activities through DOE’s Fusion Energy Sciences Advisory Committee. She and her team travel often to Washington, D.C., working with DOE and legislators to expand fusion energy research and advocacy in the nation. Livermore also leads a “Collaboratory” with other DOE national laboratories to connect research project leads and facilitate public-private partnerships. The Collaboratory has hosted multiple events with industry, and the Laboratory has partnered with three private companies who aim to design pilot IFE plants.

Meanwhile, Galbraith and other IFE leaders have served as technical advisors for engineering design teams at Texas A&M University and given them IFE-relevant problems to solve, including advanced chamber and blanket design. Galbraith is working with Nelson to develop the IFE plant design portion of a high-energy-density science summer school program, which Nelson is leading in 2025 at the University of California at San Diego, and they have developed IFE curriculum that has been deployed at six universities starting in spring 2025. “We’re hoping we can get a group of students really excited about fusion and start to build up the next generation of engineers and scientists that will make fusion a reality,” says Galbraith. The team has led IFE strategic planning exercises at the Laboratory, and Lawrence Livermore will stand up a new fusion institute—named “LIFT,” for Livermore Institute for Fusion Technology—a research and development center that will coordinate and centralize institutional fusion energy research.

Harnessing IFE will be a massive undertaking, but Livermore’s broad and deep expertise, facilities, and capabilities put the Laboratory in a unique position to lead and play an impactful role. “If we can set it up correctly, IFE will be a big piece of the Laboratory’s long-term vision,” says Ma. “IFE plays off of our history and all of our strengths, and it is critical for long-term national security.”

NASA Earth Science Division provides key data

by Dylan B. Millet, Belay B. Demoz, et al.

In May, the US administration proposed budget cuts to NASA, including a more than 50% decrease in funding for the agency’s Earth Science Division (ESD), the mission of which is to gather knowledge about Earth through space-based observation and other tools. The budget cuts proposed for ESD would cancel crucial satellites that observe Earth and its atmosphere, gut US science and engineering expertise, and potentially lead to the closure of NASA research centers. As former members of the recently dissolved NASA Earth Science Advisory Committee, an all-volunteer, independent body chartered to advise ESD, we warn that these actions would come at a profound cost to US society and scientific leadership.

Spin-filter tunneling detection of antiferromagnetic resonance with electrically tunable damping

by Thow Min Jerald Cham, Daniel G. Chica, et al.

Antiferromagnetic spintronics offers the potential for higher-frequency operations and improved insensitivity to magnetic fields compared to ferromagnetic spintronics. However, previous electrical techniques to detect antiferromagnetic dynamics have utilized large, millimeter-scale bulk crystals. Here we demonstrate direct electrical detection of antiferromagnetic resonance in structures on the few-micrometer scale using spin-filter tunneling in PtTe2/bilayer CrSBr/graphite junctions in which the tunnel barrier is the van der Waals antiferromagnet CrSBr. This sample geometry allows not only efficient detection, but also electrical control of the antiferromagnetic resonance through spin-orbit torque from the PtTe2 electrode. The ability to efficiently detect and control antiferromagnetic resonance enables detailed studies of the physics governing these high-frequency dynamics.

Scalable emulation of protein equilibrium ensembles with generative deep learning

by Sarah Lewis, Tim Hempel, et al.

Following the sequence and structure revolutions, predicting functionally relevant protein structure changes at scale remains an outstanding challenge. We introduce BioEmu, a deep learning system that emulates protein equilibrium ensembles by generating thousands of statistically independent structures per hour on a single GPU. BioEmu integrates over 200 milliseconds of molecular dynamics (MD) simulations, static structures and experimental protein stabilities using novel training algorithms. It captures diverse functional motions—including cryptic pocket formation, local unfolding, and domain rearrangements—and predicts relative free energies with 1 kcal/mol accuracy compared to millisecond-scale MD and experimental data. BioEmu provides mechanistic insights by jointly modeling structural ensembles and thermodynamic properties. This approach amortizes the cost of MD and experimental data generation, demonstrating a scalable path toward understanding and designing protein function.

Negative capacitance overcomes Schottky-gate limits in GaN high-electron-mobility transistors

by Asir Intisar Khan, Jeong-Kyu Kim, et al.

For high-electron-mobility transistors based on two-dimensional electron gas (2DEG) within a quantum well, such as those based on AlGaN/GaN heterostructure, a Schottky-gate is used to maximize the amount of charge that can be induced and thereby the current that can be achieved. However, the Schottky-gate also leads to very high leakage current through the gate electrode. Adding a conventional dielectric layer between the nitride layers and gate metal can reduce leakage; but this comes at the price of a reduced drain current. Here, we used a ferroic HfO2 – ZrO2 bilayer as the gate dielectric and achieved a simultaneous increase in the ON current and decrease in the leakage current, a combination otherwise not attainable with conventional dielectrics. This approach surpasses the conventional limits of Schottky GaN transistors and provides a new pathway to improve performance in transistors based on 2DEG.

Stability of Heteroclinic Cycles in Rings of Coupled Oscillators

[from the London Mathematical Laboratory]

Complex networks of interconnected physical systems arise in many areas of mathematics, science and engineering. Many such systems exhibit heteroclinic cycles—dynamical trajectories that show a roughly periodic behavior, with non-convergent time averages. In these systems, average quantities fluctuate continuously, although the fluctuations slow down as the dynamics repeatedly and systematically approach a set of fixed points. Despite this general understanding, key open questions remain concerning the existence and stability of such cycles in general dynamical networks.

In a new paper [archived PDF], LML Fellow Claire Postlethwaite and Rob Sturman of the University of Leeds investigate a family of coupled map lattices defined on ring networks and establish stability properties of the possible families of heteroclinic cycles. To begin, they first consider a simple system of N coupled systems, each system based on the logistic map, and coupling between systems determined by a parameter γ. If γ = 0, each node independently follows logistic map dynamics, showing stable periodic cycles or chaotic behavior. The authors design the coupling between systems to have a general inhibitory effect, driving the dynamics toward zero. Intuitively, this should encourage oscillatory behavior, as nodes can alternately be active (take a non-zero value), and hence inhibit those nodes to which it is connected to, decay, when other nodes in turn inhibit them; and finally grow again to an active state as the nodes inhibiting them decay in turn. In the simple case of N = 3, for example, this dynamics leads to a trajectory which cycles between three fixed points.

The authors then extend earlier work to consider larger networks of coupled systems as described by a directed graph, describing how to find the fixed points and heteroclinic connections for such a system. In general, they show, this procedure results in highly complex and difficult to analyze heteroclinic network. Simplifying to the special case of N-node directed graphs with one-way nearest neighbor coupling, they successfully derive results for the dynamic stability of subcycles within this network, establishing that only one of the subcycles can ever be stable.

Overall, this work demonstrates that heteroclinic networks can typically arise in the phase space dynamics of certain types of symmetric graphs with inhibitory coupling. Moreover, it establishes that at most one of the subcycles can be stable (and hence observable in simulations) for an open set of parameters. Interestingly, Postlethwaite and Sturman find that the dynamics associated with such cycles are not ergodic, so that long-term averages do not converge. In particular, averaged observed quantities such as Lyapunov exponents are ill-defined, and will oscillate at a progressively slower rate.

In addition, the authors also address the more general question of whether or not a stable heteroclinic cycle is likely to be found in the corresponding phase space dynamics of a randomly generated physical network of nodes. In preliminary investigations using randomly generated Erdős–Rényi graphs, they find that the probability of existence of heteroclinic cycles increases both as the number of nodes in the physical network increases, and also as the density of edges in the physical network decreases. However, even in cases where the probability of existence of heteroclinic cycles is high, there is also a high chance of the existence of a stable fixed point in the phase space. From this they conclude that the question of the stability of the heteroclinic cycle is important in determining whether or not the heteroclinic cycle, and associated slowing down of trajectories, will be observed in the phase space associated with a randomly generated graph.
