EPJ A Topical Collection: Precision Measurements in Nuclear Physics

Guest Editors: Klaus Blaum, Maria Jose Garcia Borge

The progress made in recent years on the precision frontier in the determination and prediction of ground and excited state nuclear properties has been amazing. The advances in technology mainly concerning ion traps, storage rings, lasers, high-precision frequency measurements, detectors, and particle beams as well as advances in atom and ion manipulation have allowed for major breakthroughs in the determination of fundamental parameters and quantities of radionuclides such as masses, electromagnetic moments, lifetimes and beta decay correlations. In a similar manner, significant progress has been made in the theoretical description of the nucleus and its properties.

EPJ Plus expands and refines scope of geophysics section to become Earth System Physics

EPJ Plus has both expanded and refined the scope of its geophysics section to become Earth System Physics, which is encompassing all topics and methodologies that view the rapidly growing field of Earth System Science through the lens of physics. The aim is to offer a platform for discussing fresh perspectives and understanding of the dynamics and scales connecting geosphere, hydrosphere, atmosphere, and biosphere and the forming of environments and climates. At the same time the new scope wishes to recognize and foster the transformative potential of deep learning in the field - the connections between data scientists and geoscientist are still developing, and physically-informed AI represents not just an evolution in methodology but a paradigm shift in how to conceptualize and engage with Earth System Science.

EPJ PV Highlight - Prioritizing Circular Economy strategies for sustainable PV deployment at the TW scale

Prioritizing Circular Economy strategies for sustainable PV deployment at the TW scale

The material demand and eventual end of life management associated with multi-TW scale photovoltaic (PV) deployment has elicited significant consternation in research communities and the public discourse. Circular Economy and it's associated R-Actions (Reduce, Reuse, Recycle) have been proposed to mitigate end of life management and material sourcing concerns. However, Circular Economy studies and metrics typically focus on a single product scale, heavily emphasize recycling, and only consider mass, excluding energy flows – a major oversight for an energy generating technology. Leveraging the open-source PV in Circular Economy (PV ICE) tool, the article quantifies the mass and energy implications of different R-Actions and proposed sustainable PV module designs in the context of achieving energy transition deployment goals (75 TW in 2050, 86 TW in 2100). Specifically, 13 technology-based module scenarios are established varying module efficiency, lifetime, and material circularity. These 13 module scenarios are evaluated across 6 metrics; total deployment including replacements, virgin material demand, lifecycle wastes, energy demands, net energy generated, and energy balance.


EPJ B Topical review - Twenty-five years of random asset exchange modeling

Over the last twenty-five years, there has emerged within the subfield of econophysics a sizeable and important literature (hereinafter the “random asset exchange” literature) concerned with the application of stochastic processes to model wealth and income distributions. In a new Topical Review published in EPJ B, written by Max Greenberg (University of Massachusetts Amherst, USA) and H. Oliver Gao (Cornell University, USA), the random asset exchange literature as a whole is comprehensively exposited for the first time.


EPJ E Highlight - Investigating collective motions in schools of zebrafish

Observations reveal new insights into the evolution of collective motions within schools of zebrafish, and how their complexity and structure vary with density.

Active systems display a wide range of complex and fascinating behaviours, many of which are not yet fully understood. Found on scales ranging from microbes and self-propelling particles to large groups of fish, birds, and mammals, they are made up of many individual parts, which each convert energy from their surroundings into motion.

Through new analysis published in EPJ E, Antonio Romaguera and collaborators at the Rural Federal University of Pernambuco, Brazil, have gained deeper insights into the collective motions of schools of zebrafish: active systems in which multiple fish can collectively move in the same direction. The team’s discoveries could help researchers to better understand the unique properties of active matter, and how complex behaviours emerge and evolve on different scales.


EPJ E Highlight - Modelling vibration patterns in granular materials

Building statistical models of grain behaviours

The ‘Laguerre ensemble’ statistical model can better describe the vibrational patterns of granular materials at a critical point of transition in their behaviour.

Granular materials are collections of solid particles which can behave in similar ways to both solids and liquids via interactions between grains. Previously, researchers have explored how the behaviours of these materials can be described in the language of statistical mechanics.

Through new research published in EPJ E , Onuttom Narayan at the University of California, together with Harsh Mathur at Case Western Reserve University, show how the characteristic vibrational patterns associated with granular materials at the point where they transition to more solid-like states can be reproduced more accurately. The work could help researchers to gain a deeper understanding of how granular materials behave.


EPJ PV Highlight - Communication on the potential of applied PV in the European Union: Rooftops, reservoirs, roads (R3)

Communication on the potential of applied PV in the European Union: Rooftops, reservoirs, roads (R3)

‘Communication on the potential of applied PV in the European Union: Rooftops, reservoirs, roads (R3)’ is a study conducted by the European Commission’s Joint Research Centre (JRC) that aims to assess the technical capacity potential of these three photovoltaic (PV) applications. The results were published recently in EPJ Photovoltaics.
Renewable energy technologies, like solar panels, are important for meeting the increasing demand for electricity and helping to combat climate change. The European Union (EU) has set ambitious targets for PV installation, but there are challenges to overcome, including competition for land and potential environmental drawbacks.
Indeed, the EU Solar Energy Strategy has outlined solid plans for PV installation, aiming for 385 GWDC (320 GWAC) by 2025 and 720 GWDC (600 GWAC) by 2030. While striving to meet these targets, it is crucial to ensure that the adoption of renewable energy sources does not adversely affect the environment and biodiversity, in accordance with EU policies on nature and wildlife conservation.
