We are pleased to inform the readers and authors of EPJ D that from now on articles published in the journal will feature a graphical abstract. While it is not meant to provide specific results, this element will serve the purpose of conveying visually the gist of the article, along with the title. Authors may use an item already present in the manuscript or a purpose-made graphic. The use of color is strongly encouraged. Images previously published under the copyright of other publishers cannot be considered.

A theoretical study shows that strong ties between light and organic matter at the nanoscale open the door to modifying these coupled systems’ optical, electronic or chemical properties.
Light and matter can be so strongly linked that their characteristics become indistinguishable. These light-matter couplings are referred to as polaritons. Their energy oscillates continuously between both systems, giving rise to attractive new physical phenomena. Now, scientists in France have explained why such polaritons can remain for an unusual long time at the lowest energy levels, in such a way that alters the microscopic and macroscopic characteristics of their constituting matter. These findings thus pave the way for optical, electronic and chemical applications. The work has been published in EPJ D by Antoine Canaguier-Durand from the University of Strasbourg, France, and colleagues.

We are pleased to announce a new editorial position for EPJD, that of North American Regional Editor. The aim of this role is to build the reputation of the journal throughout the USA and Canada, establishing further links with the ATMOP community and consolidating EPJD’s position within the field. We are delighted to announce that Professor Kurt Becker has been appointed to this position, continuing his close association with the journal and building on the exceptional work done over his five-year term as Editor-in-Chief.

December 31st, 2014 marked the end of the terms of appointment of two of the Editors-in-Chief for EPJD, Professor Kurt Becker (New York University, USA) and Professor Nigel Mason (Open University, UK). Profs Becker and Mason have served as Editors-in-Chief since 2009, representing the fields of plasma physics and atomic and molecular physics respectively. Under their leadership the journal has seen substantial growth and development across a broad range of topical areas, with special issues published in diverse fields including microplasmas, electron-positron collision physics, cluster physics and radiation biodamage. The publishers would like to express their sincere appreciation to Kurt and Nigel for their service to the journal and the wider community as Editors-in-Chief over the past five years.
We are delighted to announce the appointment of their successors, starting from 1st January 2015.

The aim of quantum information research is to harness the distinctive features of quantum physics, especially superposition and entanglement, to enhance the functionality and power of information and communication technologies. It has been a thriving interdisciplinary field of research for the last thirty years, extending from the fundamental investigation of quantum phenomena to the experimental implementation of disruptive quantum-enabled technologies.

A new study focuses on the collective dynamics of illuminated atoms coupled to photons travelling in a nanofiber
Theoretical physicists have uncovered the existence of self-organised dynamics of atoms, bound by light into a crystal, with long range atom-atom interactions. These findings were recently published in EPJ D by Daniela Holzmann from the University of Innsbruck, Austria, and colleagues. This approach could, among others, help to better understand the process of crystallisation in new materials, and help implement efficient photon storage and precision measurements. Applied to ultra-cold atoms, it could aid in the study of long-distance interactions in the quantum dynamics of one-dimensional non- conventional materials, referred to as exotic matter.

In this EPJ D Colloquium, the authors review the multiscale approach to the assessment of biodamage that results from the irradiation of biological media with ions. This approach is explained in depth and compared to other approaches. The ion propagation processes that take place in the medium concurrent with ionisation and excitation of molecules, transport of secondary products, dynamics of the medium, and biological damage, take place on a number of different temporal, spatial and energy scales. The multiscale approach, a physical phenomenon-based analysis of the scenario that leads to radiation damage, has been designed to consider all relevant effects on a variety of scales and to enable quantitative assessment of biological damage as a result of irradiation with ions.

In this EPJ D Colloquium, the authors discuss the main principles, achievements and perspectives in the fields of highly-parallel luminescence spectroscopy and the imaging of single molecules (SMs) in transparent solids. Special attention is given to SM detection at low temperatures, where ultranarrow and bright zero-phonon lines (ZPLs) can be generated by emitting centres for observation.

The Casimir electromagnetic fluctuation forces across plasmas are analogous to so-called weak nuclear interaction forces, as new findings showA new theoretical work establishes a long-sought-after connection between nuclear particles and electromagnetic theories. Its findings suggests that there is an equivalence between generalised Casimir forces and what are referred to as weak nuclear interactions between protons and neutrons. The Casimir forces are due to the quantisation of electromagnetic fluctuations in vacuum, while the weak nuclear interactions are mediated by subatomic scale particles, originally called mesons by Yukawa. These findings by Barry Ninham from the Australian National University, in Canberra, and European colleagues, have now been published in EPJ D.

A new theoretical study demonstrates for the first time that quantum holograms could be a candidate for becoming quantum information memory
Russian scientists have developed a theoretical model of quantum memory for light, adapting the concept of a hologram to a quantum system. These findings are included in study just published in EPJ D, by Anton Vetlugin and Ivan Sokolov from St. Petersburg State University in Russia. The authors demonstrate for the first time, that it is theoretically possible to retrieve, on demand, a given portion of the stored quantised light signal of a holographic image—set in a given direction in a given position in time sequence.
