EPJ Plus – New analytic method to solve 2-d Helmholtz equation for irregular boundaries

To date the most successful efforts to solve the irregular boundary Helmholtz equation with Neumann boundary conditions have been computational, but even this general method has its drawbacks. Panda et al. provide a new analytic approach which solves the irregular boundary problem via a perturbative series. As the authors show by working out several nontrivial examples, the benefits of this approach include a precise understanding of the behavior of the solution as the amplitude of the boundary distortion is increased, as well as the control over the analytic precision in the terms computed and its corresponding analytic error estimates. more

EPJ Plus – Focus on Hadron Therapy in Europe

Oncological hadron therapy was first proposed 65 years ago by Robert R. Wilson, and it took more than 40 years to build the first dedicated facility, in Loma Linda in the nineties. The growth of new facilities since then has been exponential, and thousands of patients are now treated every year. Close collaboration between research institutes, clinical centers and industry is the basis and the future of this field. This EPJ Plus focus issue spotlights the status of hadron therapy in Europe, where different centers are already in operation, some are just now ready to start patient treatments, and new ones are being planned. more

EPJ E - Compare Motor Models: Two-State versus Crossbridge

Rigid two-state and crossbridge are two models of motor assemblies widely used in the literature. But up to now they had never been studied and compared systematically. In cells, motor proteins use chemical energy to generate motion and forces. This thorough comparison presented in EPJE shows that theforce response to a small displacement step is similar in both models to the delayed stretch activation observed in oscillating muscles.


EPJ B welcomes a new Editor-in-Chief for its complex systems section

EPJB - new Editor-in-Chief Peter Hänggi

The publishers of The European Physical Journal B - Condensed Matter and Complex Systems are pleased to announce the appointment of Professor Peter Hänggi as a new Editor-in-Chief, who will specifically contribute to the further development of the physics of complex systems section of the journal.


EPJ B - Deciphering complex games

EPJ B - Deciphering complex games

Game theory has changed our way of thinking about socio-economic interaction, shedding light on the consequences of leaving individuals take their choices for the sake of their self-interest. As exemplified by the prisoner's dilemma, the prediction of this approach can be quite far from what welfare optimization would predict.


EPJ Plus – Alternative Electroweak Model without a Higgs

While the hunt is on for the Higgs at the LHC, model building continues to explore also other scenarios. Here, an ultraviolet complete electroweak model is presented that assumes running coupling constants described by energy-dependent entire functions. Contrary to the conventional formulation the action contains no physical scalar fields and no Higgs particle, even if the foreseen masses for particles are compatible with known experimental values.


EPJ D - Speedier Quantum Logic

EPJD - Speedier Quantum Logic

Quantum information processing requires logical operations with multiple quantum bits. One route to this goal is controlling each qubit with a time-dependent external magnetic field. In this recent paper published in EPJ D, Heule et al. describe ways to perform logical operations on an ENTIRE superconducting qubit chain by controlling just ONE of the end qubits of the chain.


EPJ B – Round-up on the conductivity of carbon nanomaterials

An 8-unit-cell long (10, 0) CNT end-contacted with Au(111) metallic electrodes

A new Colloquium article by I. Deretzis and A. La Magna published in EPJB reviews the possibilities offered by all-carbon electronics as well as elucidating drawbacks in view of future applications.
