Can a few fanatics influence the opinion of a large segment of a society?

Stauffer, D.; Sahimi, M. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 2, pp. 147-152

Models that provide insight into how extreme positions regarding any social phenomenon may spread in a society or at the global scale are of great current interest. A realistic model must account for the fact that globalization, internet, and other means of mass communications have given rise to...

Quantum Brownian motion and the second law of thermodynamics

Kim, ILki; Mahler, Günter - In: The European Physical Journal B - Condensed Matter and … 54 (2006) 3, pp. 405-414

We consider a single harmonic oscillator coupled to a bath at zero temperature. As is well-known, the oscillator then has a higher average energy than that given by its ground state. Here we show analytically that for a damping model with arbitrarily discrete distribution of bath modes and...

The second law of thermodynamics in the quantum Brownian oscillator at an arbitrary temperature

Kim, I.; Mahler, G. - In: The European Physical Journal B - Condensed Matter and … 60 (2007) 3, pp. 401-408

In the classical limit no work is needed to couple a system to a bath with sufficiently weak coupling strength (or with arbitrarily finite coupling strength for a linear system) at the same temperature. In the quantum domain this may be expected to change due to system-bath entanglement. Here we...

Long-range effects on superdiffusive algebraic solitons in anharmonic chains

Brunhuber, C.; Mertens, F. G.; Gaididei, Y. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 1, pp. 57-65

Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Kac-Baker form. The variance of the soliton position shows a stronger than linear time-dependence (superdiffusion) as...

A multichannel shot noise approach to describe synaptic background activity in neurons

Rudolph, M.; Destexhe, A. - In: The European Physical Journal B - Condensed Matter and … 52 (2006) 1, pp. 125-132

Systems driven by Poisson-distributed quantal inputs can be described as “shot noise” stochastic processes. This … longer be described by classical shot noise processes. Here, we show that explicit expressions for various statistical … temporal correlations and the statistics of fluctuations. Multi-channel shot noise processes, therefore, open a way to deduce …
