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.

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.

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.

Individual success in competitive endeavors, such as sports or academia, is the result of many factors, some of which are time-dependent. In order to compare human achievements from different time periods, we need to normalize success metrics so as to avoid a time-dependent bias in the comparison of the statistical measures. A novel 'detrending' approach presented in EPJ B removes precisely this bias and allows for an objective comparison across time.

Gold and copper atoms adsorbed on a NaCl surface behave as isolated atoms and complex electronic interactions with the surface are negligible. A study by a group of Brazilian researchers uses first-principles simulations to measure the electronic and magnetic properties of gold and copper atoms adsorbed on NaCl(001) surfaces, as well as the modifications in these properties upon charge injection.

A Colloquium paper by McEniry et al. published in EPJ B surveys the theory and applications of a new family of computational methods, namely Correlated Electron-Ion Dynamics, which enable the simultaneous evaluation of the electronic current, along with the current-induced forces and subsequent motion of the nuclei.
