EPJ B - Turbulences at a standstill

Energy flowing from large-scale to small-scale places may be prevented from flowing freely in specific conditions.

For theoretical physicist Dima Shepelyansky from the CNRS-University of Toulouse, France, devising models of chaos and turbulence is his bread and butter. In a recent study published in EPJB, he presents an exception he found in a model of turbulence, indicating that there are energy flows from large to small scale in confined space. Indeed, under a specific energy threshold, there are no energy flows, similar to the way electron currents and energy spreading are stopped in disordered solids.

EPJ B has a new Editor in Chief to handle theory and simulations in condensed matter

Angel Rubio new EPJ B Editor in Chief to handle theory and simulations in condensed matter

From July 2012 Angel Rubio succeeds Luciano Colombo as Editor in Chief of EPJ B for the part of condensed matter theory and modeling. Professor Rubio is the head of the NanoBio spectroscopy group at the Universidad del País Vasco in Spain and leader of the theoretical spectroscopy group at the Fritz Haber Institut in Berlin. His group collaborates with many other experimental and theoretical research groups, as well as groups from industry. He has contributed with a large number of publications to the development of novel theoretical tools to investigate the electronic response of solids, nanostructures, biomolecules and hybrid materials to external electromagnetic fields. He has numerous honors and awards to his name which he garnered throughout his academic career.

EPJ B - Cell dynamics simulations: a fast way to profile block copolymers

Cell Dynamics Simulation (CDS) is a fast and efficient method for the simulation of kinetic processes in large-scale phase separation systems.

We review the application of this method to block copolymer systems and illustrate its use by examining a set of physical phenomena occurring in these systems. In spite of the simplicity of the model, such applications of CDS demonstrate that it is capable of accurately describing complex phenomena and is, therefore, a complementary method which can serve as a precursor to slower, more elaborate techniques.

EPJ B - Spurious switching points in traded stock dynamics

A selection of biased statistical subsets could yield an inaccurate interpretation of market behaviour and financial returns.

Physicists have rebuffed the existence of power laws governing the dynamics of traded stock volatility, volume and intertrade times at times of stock price extrema. They did this by demonstrating that what appeared as “switching points” in financial markets trends was due to a bias in the interpretation of market data statistics. This study by Vladimir Filimonov and Didier Sornette from the Department of Management, Technology and Economics at ETH Zurich in Switzerland has just been published in EPJB.

EPJ B - Superconducting stripe could become an ultra-low-voltage sensor

Minute-scale interactions govern electronic behaviour of superconductors with potential applications for voltage measurement techniques.

Researchers studying a superconducting stripe observed an intermittent motion of magnetic flux which carries vortices inside the regularly spaced weak conducting regions carved into the superconducting material. These vortices resulted in alternating static phases with zero voltage and dynamic phases, which are characterised by non-zero voltage peaks in the superconductor. This study, which has just been published in EPJB, was carried out by scientists from the Condensed Matter Theory Group of the University of Antwerp, Belgium, working in collaboration with Brazilian colleagues.

EPJ B - Quantum information motion control is now improved

Model simulates closer control over the transport of information-carrying electrons.

Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper has been published in EPJB. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons.

EPJ B - Market exchange rules responsible for wealth concentration

Next year’s Davos meeting could benefit from physicists’ insights on how new market rules help avoid wealth concentration.

Two Brazilian physicists have shown that wealth concentration invariably stems from a particular type of market exchange rules – where agents cannot receive more income than their own capital. The authors concluded that maximum inequalities ensue from free markets, which are governed by such seemingly fair rules. This study, published in EPJB was conducted by J. Roberto Iglesias and Rita de Almeida from the Brazilian National Institute of Science and Technology of Complex Systems, based in Porto Alegre. This Brazilian city is famous for hosting the World Social Forum, which is designed to find alternatives to economic liberalism.

EPJ B - Tiling pattern governs quasicrystals’ magnetism

Review sheds light on the underlying magnetic qualities stemming from quasicrystals’ complex structure.

Few material classes have generated as much interest as quasicrystals. In a review published in EPJB quasicrystal expert Anuradha Jagannathan, from Paris-Sud University in Orsay, France, outlines the progress to date in the theory explaining the magnetic properties of these quasicrystals.

EPJ B - Brain capacity limits exponential online data growth

Study of internet file sizes shows that information growth is self-limited by the human mind.

Scientists have found that the capacity of the human brain to process and record information - and not economic constraints - may constitute the dominant limiting factor for the overall growth of globally stored information. These findings have just been published in an article in EPJB by Claudius Gros and colleagues from the Institute for Theoretical Physics at Goethe University Frankfurt in Germany.

EPJ B - Harnessing the predictive power of virtual communities

Reducing the disconnect between virtual network models and real-life communities.

Scientists have created a new algorithm to detect virtual communities, designed to match the needs of real-life social, biological or information networks detection better than with current attempts. The results of this study by Lovro Šubelj and his colleague Marko Bajec from the University of Ljubljana, Slovenia have just been published in EPJB.
