Study quantifies effects of electric field-induced versus conventional heating
The effect of microwave heating and cell phone radiation on sample material is no different than a temperature increase, according to scientists from the Department of Chemistry and Biochemistry, Arizona State University, in Tempe, as published in a recent issue of EPJ B.

How nickel-titanium nanometric-size particles change back to their memorised shape
University of Constance physicists Daniel Mutter and Peter Nielaba have visualised changes in shape memory materials down to the nanometric scale in an article published in EPJB.EPJ B – Online activity grows in a similar pattern to those of real-life networks

The activity of online communities does not grow in line with the number of users, according to a model recently published in the European Physical Journal B.
The Internet has given rise to its own sorting devices. Among these, tagging consists in assigning user-chosen keywords to a piece of information (such as a digital image) to facilitate searches. Lingfei Wu, a researcher at the City University of Hong Kong’s Department of Media and Communication, used the tagging behaviour of social media application users to study the growth of online communities’ activity.EPJ B - Atomistic details over longer time scales
- Details
- Published on 22 August 2011
The conventional method for atomistic simulation, namely molecular dynamics (MD), is not well suited to resolve slow dynamical processes, that is processes associated with a system that gets trapped from time to time in deep local energy minima.
In a Colloquium paper in the European Physical Journal B, A. Kushima, J. Eapen, Ju Li, S. Yip and T. Zhu review the capabilities of biased molecular simulation methods such as metadynamics, autonomous basin climbing (ABC), strain-boost and adaptive boost simulations – methods designed to probe at the atomic level mechanisms that drive system-level behavior observable on macroscopic time scales.
EPJ B - Disordered networks synchronise faster than small world networks
- Details
- Published on 22 August 2011
A study recently published in European Physical Journal B presents observations of how complex systems synchronise over time.
Synchronisation occurs when individual elements in a complex network behave in line with each other. This applies to real-life examples such as the way neurons fire during an epileptic seizure or the phenomenon of crickets falling into step with one another.

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

- Published on 15 June 2011
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.

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.
EPJ B – New theory predicts dispersion in porous solids
- Details
- Published on 08 April 2011
Modeling the transport of fluids in porous solids is a problem of general interest for its implications in construction engineering, industrial catalysis, hydrology, agriculture and geology. The classical approach uses an equation derived from continuum mechanics which is problematic and often gives incorrect predictions. When the porous medium presents many scales of variability the problem becomes intractable.

- Published on 15 March 2011
Constant-pressure molecular dynamics simulations allow the study of systems where external pressure is a driving force for a structural transformation.
