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 …

On statistical properties of traded volume in financial markets

Souza, J. de; Moyano, L. G.; Queirós, S. M. Duarte - In: The European Physical Journal B - Condensed Matter and … 50 (2006) 1, pp. 165-168

In this article we study the dependence degree of the traded volume of the Dow Jones 30 constituent equities by using a nonextensive generalised form of the Kullback-Leibler information measure. Our results show a slow decay of the dependence degree as a function of the lag. This feature is...

Thermal radiation and near-field energy density of thin metallic films

Biehs, S.-A.; Reddig, D.; Holthaus, M. - In: The European Physical Journal B - Condensed Matter and … 55 (2007) 3, pp. 237-251

We study the properties of thermal radiation emitted by a thin dielectric slab, employing the framework of macroscopic fluctuational electrodynamics. Particular emphasis is given to the analytical construction of the required dyadic Green's functions. Based on these, general expressions are...

Reciprocating nanoengine

Makhnovskii, Yu. A.; Rozenbaum, V. M.; Yang, D.-Y.; … - In: The European Physical Journal B - Condensed Matter and … 52 (2006) 4, pp. 501-505

Brownian motion in a confining potential fluctuating between two spatially separated potential profiles is considered as a model of an engine converting nonequilibrium fluctuations into reciprocating motion on the nanoscale. We present two exact solutions obtained for the parabolic and step...
