Energy plays a crucial role in economic development and stability. The establishment of the European Coal & Steel Community in 1951 and Euratom in 1957 reflected the recognition of energy’s importance in shaping Europe’s future. European Union (EU) energy policy decisions are driven by a combination of technical, economic, environmental, political, legal and societal factors. Currently, fossil fuels supply approximately 80% of the world’s primary energy, a figure that has remained stable over the past 30 years [1]. Given the finite nature of these resources and the impact of fossil fuels on the global environment, transitioning to alternative solutions is an important consideration, particularly for the EU, which imports around 80% of its gas and over 90% of its oil [2]. Following the Paris Agreement (2015), the EU is committed to decarbonisation and is leading the path in this respect. From 1990 to 2022 the EU-27 reduced greenhouse gas (GHG) emissions [3, 4] by 33%. Over the same period, its share of global emissions dropped from 16% to 7%, due to the implementation of EU energy policies, industrial carbon leakage [5], and development of other nations. Meanwhile, global emissions increased by 65% between 1990 and 2022 [6]. The partial decarbonisation of the electricity sector contributed to this significant GHG emission reduction in the EU, notably through wind, solar and nuclear technologies, with fossil fuel backup systems, necessary to bridge the gap, in order to address the variability of the renewable components. To continue reducing its emissions and reach net zero by 2050, the EU plans to increase its share of Variable Renewable Energy Sources (VRES), requiring, according to the most recent estimate by the European Commission, of the order of €10 trillion of investment by 2040 [7]. While VRES technologies contribute to decarbonisation, increasing their share of the electric energy market poses significant challenges. Ensuring a continuous, affordable, and reliable energy supply requires the following points to be addressed: The Draghi report [12] has recently highlighted the negative economic and industrial impacts of the current energy transition policies, including considerations related to increase of energy costs, technological innovation, and supply chain dependencies. Effective energy policies must indeed balance three key factors, namely (a) security and reliability of energy supply, (b) low energy cost for households and industry, (c) minimal impact of energy systems on both local and global ecosystems. Given the decarbonisation level that the EU has already reached, and points (i)-(iv) above, we recommend shifting priorities to enhance security of supply, affordability and sustainability of the energy system, considering the following points: By considering a balanced approach that integrates diverse energy solutions, technological advancements, and economic sustainability, the EU can develop an energy strategy, a critical element of a global strategy, currently missing, that supports long-term prosperity while affirming its commitment to environmental responsibility.

The highlighted article is part of the Topical Issue on ‘EU PVSEC 2024: State of the Art and Developments in Photovoltaics’, edited by Robert Kenny and Gabriele Eder EPJB highlight: Unlocking next-gen optoelectronic with InSb/WSSe heterostructures The Editors-in-Chief of EPJB propose to highlight the paper: Study on the electronic structure and optical properties of InSb/WSSe van der Waals heterostructure, by Su, S., Zhao, X., Wang, X. et al. In this new research published in EPJ B, Weibin Zhang and colleagues at Yunnan Normal University demonstrate that heterostructures made from alternating layers of InSb and WSSe are highly suited for light absorption. If confirmed experimentally, these properties could make the material a valuable platform for harvesting light across a broad range of wavelengths—potentially paving the way for next-generation optoelectronic devices. The researchers hope their findings will provide a solid theoretical foundation for future experiments—bringing the practical use of these heterostructures one step closer. EPJ D Highlight – Improving simulations of the PIII process The paper highlighted by the Editors-in-Chief of EPJD is Numerical simulation of the PIII process considering temperature-dependent thermophysical properties in a viscous sheath, by Sattari, M., Ghasemi, J. (Eur. Phys. J. D 79, 49 (2025). Through new research published in EPJ D, Mohammadreza Sattari and Jalal Ghasemi at the University of Zanjan, Iran, present an improved approach to simulating ion dynamics within the sheath. Their results show that when variations in ion velocities driven by temperature and viscosity are included, higher currents flow perpendicular to the normal target surface. At the same time, ion kinetic energy falls by more than 20% compared with simpler models – a finding with important implications for improving PIII performance.

Declaration for the Future
On 14th November, the German Physical Society (DPG) and the Physical Society of Japan (JPS) signed a common “Declaration for the Future” warning on any use of nuclear weapons. In their “Declaration for the Future”, the JPS and the DPG warn that any use of nuclear weapons would have extremely serious consequences. Furthermore, they argue that nuclear armament already entails considerable risks. The societies advocate using scientific knowledge for peaceful purposes and for shaping a future worth living. In this context, they acknowledge the special responsibility of physicists.On the one hand, their research has enabled the development of nuclear weapons, but on the other hand, they have special expertise, such as that required for the control of nuclear weapons or the monitoring of disarmament efforts. Both societies invite physical societies and academic organizations worldwide to join them in this commitment. The declaration can be downloaded here, as well as from the DPG webpage where you will also find some photos of the ceremony at the Town Hall of the City of Münster: https://www.dpg-physik.de/veroeffentlichungen/aktuell/2025/gemeinsame-erklaerung-gegen-atomare-bedrohungen-unterzeichnet

Heinrich Hertz Lecture Hall at KIT named as an EPS Historic Site
Authors: Guido Drexlin and Thomas Muller On October 30 2025, the European Physical Society (EPS) conferred the award `EPS Historic Site´ on the Heinrich Hertz Lecture Hall at the Karlsruhe Institute of Technology (KIT) in recognition of the series of ingenious experiments carried out at this site in 1886 by Heinrich Hertz. This newest EPS Historic Site, still being in regular use today for lectures at KIT, formed the ideal surroundings for a highly instructive view on the foundational research by Hertz. It also allowed putting the excellence of the physical sciences in Karlsruhe on a map in Europe and beyond. The first observation of electromagnetic waves by Heinrich Hertz, sent and received by antennae, successfully tested the laws of electromagnetism as described by Maxwell´s equations. Beyond that, it marks a seminal event in the history of physics and engineering that has paved the ground for the development of technologies that have been transformative for modern societies. Heinrich Hertz held a position as Professor of physics from 1885 to 1889 at the Technical University of Karlsruhe, a predecessor institution of KIT. His experiments were carried out at today’s Heinrich Hertz Lecture Hall, in close proximity to a Memorial dedicated to his legacy. On the 100th anniversary of the unveiling of that memorial on October 30, 1925 a special EPS Colloquium honoured the achievement of Hertz with a series of talks. The convenors of the fully packed symposium, Guido Drexlin and Thomas Müller from KIT, put together a series of talks and key notes, reviewing the fundamental relevance of Heinrich Hertz then and now, including a lively experimental demonstration of his breakthrough experiment. The highlight of the Colloquium was marked by the unveiling of the commemorative plaque by several attendees, including the Presidents of the EPS, Professor Mairi Sakellariadou, and of the DPG, Professor Klaus Richter, as well as KIT´s Vice President Academic Affairs, Professor Oliver Kraft. The latter emphasised that `The discovery of electromagnetic waves by Heinrich Hertz has been fundamental for wireless communication. Many of today´s technologies such as television, mobile phone communication, or WLAN would not be conceivable without this discovery. KIT takes pride in receiving the EPS Historic Site Award today´. Following the festive ceremony, the commemorative plaque will be placed in due time at the Ehrenhof of KIT next to the memorial of Heinrich Hertz as an inspiration for future generations of scientists.

LHC Collaborations at CERN Win the 2025 Breakthrough Prize in Fundamental Physics
Author: Anna Di Ciaccio The four major international collaborations at CERN’s Large Hadron Collider — ATLAS, CMS, ALICE and LHCb — have been jointly awarded the 2025 Breakthrough Prize in Fundamental Physics, in recognition of their outstanding contributions to advancing our understanding of the fundamental laws of nature. The prize honours the achievements of thousands of scientists, engineers and technicians from more than 70 countries, whose collective work during the LHC’s second data-taking run has delivered groundbreaking results in particle physics. Their research has deepened knowledge of the Higgs boson, explored the quark–gluon plasma, and revealed new insights into matter–antimatter asymmetries and the structure of hadrons. The ATLAS and CMS collaborations were recognized for precision studies of the Higgs boson and its role in the mechanism that gives mass to fundamental particles. ALICE was honoured for its investigations of the primordial state of matter that existed shortly after the Big Bang, while LHCb was celebrated for its discoveries in flavour physics and for testing fundamental symmetries. The $3 million prize will be donated in full to the CERN & Society Foundation, which will allocate the funds to support doctoral fellowships and training opportunities for young researchers at CERN, helping to inspire and equip the next generation of scientists. The Breakthrough Prize, established in 2012, is among the most prestigious distinctions in science, celebrating major achievements in fundamental research. This year’s award acknowledges both the scientific excellence and the global spirit of cooperation that define CERN’s mission. The Breakthrough Prize winners are selected by selection committees made up of previous laureates. The cash for the prize is provided by personal foundations founded by Sergey Brin & Anne Wojcicki, Mark Zuckerberg & Priscilla Chan, and Yuri & Julia Milner, among others. This recognition also resonates within the European Physical Society (EPS) community. Three members of the EPS Executive Committee — Anna Di Ciaccio (ATLAS), Alessandra Fantoni (ALICE) and Ulrich Husemann (CMS) — are active participants in the LHC collaborations. Their involvement underlines the strong connection between CERN’s pioneering research and the broader European physics community represented by the EPS, united by a shared commitment to collaboration, excellence, and the advancement of science.

EPS Young Minds: Speed Date With Research 7.0
Author: Francesco Di Pasquale – Milan PYMP On September 27th, the Politecnico di Milano hosted the seventh edition of Speed Date with Research, a workshop that aims to connect students with the research environment. In its seventh edition, the workshop gave students a chance to learn about numerous research opportunities and hear about potential thesis projects. Speed Date with Research is a yearly event of the Student Chapter of Politecnico di Milano, in collaboration with the Physics Department. The event is designed to give students a better idea of the research being conducted in the department and the kind of thesis projects offered. The approach is simple but effective: the students have short, timed meetings with researchers, in which they can hear about different research areas and ask questions about potential thesis projects. This year’s session, Speed Date with Research 7.0 was a great success, allowing students to interact directly with researchers and feel the work going on in the Department of Physics. It included 80 master students of the Engineering Physics course of study, who were all eager to get more information about research in their field. They were able to interact with 41 researchers, one from each of the Department of Physics laboratories. The session was held in eight 10-12 minute sessions, with students rotated through the different researchers. Each session had one of the researchers give a quick pitch of their research and thesis topics available, and then students could ask questions in order to learn more. One of the major aims of the event was to spark the curiosity of the students. Through the experience of researchers and information about their work, students were encouraged to find out something that indeed interested them. The intention was to convey to them the driving force behind research itself, the passion of discovery and the motivation to pursue new ideas. The hope was that each student would have a clearer sense of direction for their course of academic pursuit when they left the event and perhaps a new spark of interest to carry them on. In short, Speed Date with Research 7.0 provided the Politecnico di Milano physics students with an enriching experience. It provided them with a chance to learn more about the research undertaken in the Department of Physics and possible thesis subjects in a personal and interactive way.
Physics is driving Europe’s economy
The European Physical Society released a new Cebr report about “The Importance of Physics for the Economies of Europe” Brussels, 4th November 2025 The European Physical Society (EPS) and the Centre for Economic and Business Research (Cebr) have released the third edition of the report “The Importance of Physics to the Economies of Europe”. An update to the previous version released in 2019, this report covers the years 2016-2022 and details the impact of physics-based businesses on the economy of the EU member states, three EFTA countries and the UK. The report demonstrates that physics is not only a scientific field—it is a strategic driver of growth, productivity, and resilience. The report shows that physics-based industries had €7.07 trillion in turnover in 2022 and contributed €2.30 trillion in Gross Value Added (GVA) in 2022. Physics based industries are resilient with a strong post-pandemic recovery in business creation, employment and output. Whilst Germany as the EU’s largest economy dominates in absolute terms, physics-based industries make up significant proportions of the economies of other European countries, for example more than one in six Swiss workers and over 15% of workers in the Czech Republic, Slovenia and Slovakia were employed around physics-related activities in 2022. Physics based industries directly support 20.1 million jobs, and productivity of workers in these industries is 68% higher than the European average. The report highlights that the physics-based sector has increased its investment in research and development (R&D) activities by 36.5% since 2016 excluding internal investments in R&D activities which cannot be quantified. Prof. Mairi Sakellariadou, the EPS President says “the report demonstrates that investment in physics research and education translates into quantifiable benefits to the European economy. The highly skilled workforce in this sector is extremely productive, and we should support future generations to work in these industries” Owen Good, Director and Head of Economic Advisory at Cebr said “Our findings demonstrate the continued economic value that the physics community bring to the European economy. Since we last conducted similar analysis in 2018, we have found a significantly increased economic contribution, with the physics-based sector employing over 20 million people and directly contributing over €2.3 trillion to the European economy in 2022. Underpinning this contribution is a strong post-COVID recovery, with the sector rebounding well to pre-pandemic levels of economic activity.” About the EPS The European Physical Society (EPS) is a not-for-profit association whose members include 42 National Physical Societies in Europe, individuals from all fields of physics, and European research institutions and physics-based companies. As a learned society, the EPS engages in activities that strengthen ties between physicists in Europe. As a federation of National Physical Societies, the EPS advocates for issues of common interest to all European countries relating to physics research, science policy and education.
