EPJ D Topical review - Theory and molecular simulations of plasma sputtering, transport and deposition processes

One shot atomistic simulations of sputtering deposition

A new Topical Review published in EPJD provides an overview of the basic theory of sputtering with recent models, focussing in particular on sputtered atom energy distribution functions. Models such as Monte-Carlo, kinetic Monte-Carlo, and classical Molecular Dynamics simulations are presented due to their ability to describe the various processes involved in sputtering, transport and deposition processes.

EPJ E Highlight - Machine learning could help kites and gliders to harvest wind energy

Powering a ship with a kite

Using trial-and-error, machine learning algorithms could enable flying wind harvesters to dynamically adjust their orientations, allowing them to account for unpredictable turbulence and improve their performances.

Airborne wind energy (AWE) is a lightweight technology which uses flying devices including kites and gliders to harvest power from the atmosphere. To maximise the energy they extract, these devices need to precisely control their orientations to account for turbulence in Earth’s atmosphere. Through new research published in EPJ E, Antonio Celani and colleagues at the Abdus Salam International Center for Theoretical Physics, Italy, demonstrate how a Reinforcement Learning algorithm could significantly boost the ability of AWE devices to account for turbulence.

EPJ Plus Focus Point on Memristive Chaotic Circuits and Systems

Guest Editors: Qiang Lai, Xiao-Wen Zhao & Jacques Kengne

The memristor was theoretically postulated by Chua in 1971 and physically realized by the HP Labs team in 2008. Its unique nonlinear features actively promote the generation of chaos and other interesting dynamical behavior and sets new challenges in applications. This topical issue aims to collect some new ideas, methods, and recent results so as to shed some light on the future research directions concerning the design, analysis, and novel applications of related chaotic systems. Overall it makes a timely and valuable contribution to broadly advancing science and technology using memristors and memristive circuits.

EPJ D Highlight - Alain Aspect: The physicist who made entanglement an experimental reality

Aspect’s 1983 thesis revolutionised quantum mechanics. https://en.wikipedia.org/wiki/Alain_ Aspect#/media/File:Alain_Aspect_ (26341660894)_(cropped).jpg

For Einstein and other physicists of his generation, the strongly counter-intuitive features of quantum mechanics were very hard to accept, given that our intuition is based on the classical world around us. This EPJ D Topical Issue examines the discoveries, motivations, and continuing legacy of Alain Aspect: the physicist whose experiments, along with those of John Clauser and Anton Zeilinger, have made that quantum entanglement, an essentially non-classical feature, is now also an experimental reality, exploited in science and technology.

An extensive network of cosmic ray detectors allows high school students in Italy to contribute to cutting-edge particle physics research

Citizen science projects offer the general public, or segments of that public such as school students, an opportunity to take part in scientific research. The Extreme Energy Events (EEE) Project in Italy is a cooperation between particle physicists studying cosmic rays and school students, and their teachers, throughout the country.

This has the twin aims of bringing cosmic ray research into schools and setting up a country-wide ‘open laboratory’ of particle detectors. One of the lead researchers from the EEE Project consortium, Silvia Pisano of the Italian Centro Fermi and Laboratori Nazionali di Frascati of INFN, Rome, Italy, has summarised the results from about 20 years of this project in a new paper in EPJ Plus.

EPJ Plus Focus Point on Uncertainty Quantification of Modelling and Simulation in Physics and Related Areas: From Theoretical to Computational Techniques

Guest Editors: Juan Carlos Cortés, Tomás Caraballo, Carla M.A. Pinto

The main goal of this topical article collection is to present new advances on theoretical and computational techniques for uncertainty quantification of modelling and simulation in relevant problems appearing in physics sciences. Many important laws in Physics are formulated by means of equations -mainly differential equations- whose input data is set after experimental measurements, therefore containing uncertainties. Apart from this fact, there often are model parameters whose nature is not known deterministically but randomly because of ignorance and inherent complexity of the physical phenomenon under study. This approach motivates the necessity of treating classical equations in Physics by considering uncertainties in their formulations. This approach is currently a cutting-edge topic whose rigorous analysis requires to masterly combine Physics, Probability and Computing, not just to solve exact or numerically the corresponding equations but also to correctly estimate model parameters, perform accurate simulations and interpret the results.

EPJ Plus Focus Point High-Energy Accelerators: Advances, Challenges, and Applications

Guest Editors: R. B. Appleby, A. Bazzani, M. Giovannozzi & E. Levichev

In this Focus point issue we look at the frontiers of beam dynamics in particle accelerators. These machines are unique scientific tools that provide focused high-density beams of sub-atomic particles such as electrons, protons or ions, at energies unparalleled in any other areas of laboratory-based science. They have been applied to vast range of problems in the last century or so, with circular colliders playing a special role in discovering new particles and new physics, with energy and particle collision rates of several orders of magnitude higher than those of pioneer colliders in the early 1960s. This Focus Point issue covers the field of particle beam physics, with a loose classification into the categories of advances in the field, challenges, and broader applications. This includes exciting topics such as non-linear beam dynamics, the Large Hadron Collider, the SuperKEKB, and the Future Circular Collider, the physics that occurs when two beams collide and some papers on the future advances of the field. We hope this issue is both exciting and inspiring for our community, and of interest beyond our community as well.

EPJ B Topical Issue on Recent developments in the functional renormalization group approach to correlated electron systems

Guest editors: Carsten Honerkamp, Dante Kennes, Volker Meden, Michael Scherer and Ronny Thomale.

This Topical Issue of EPJ B brings together a collection of articles on the recent progress of the application of the functional renormalization group to correlated electron systems.

In condensed-matter physics strong correlations between electrons in materials and devices are responsible for the formation of many intriguing emergent phenomena, including various types of magnetism, (unconventional) superconductivity, Kondo-like effects or interaction-induced topological phases. Theoretical progress in the understanding of correlated electron systems requires the dedicated development of modern and powerful quantum many-body methods. One rather versatile method is the functional renormalization group, which has recently witnessed major methodological advances and extensions. This includes aspects of the renormalization group formulation, increased computer power and enhanced interlinks to ab initio quantum material methods, extensions to novel strongly correlated electronic models, and electronic systems out of equilibrium.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
