Diffusion in flashing periodic potentials

Spagnolo, B.; Dubkov, A. - In: The European Physical Journal B - Condensed Matter and … 50 (2006) 1, pp. 299-303

-reversible noise is analyzed. The calculation of the effective diffusion coefficient is reduced to the mean first passage time problem … supersymmetric potential modulated by: (i) an external white Gaussian noise and (ii) a Markovian dichotomous noise. For both cases … in the absence of thermal noise. For rectangular potential the diffusion slows down, for all parameters of noise and of …

The power of choice in growing trees

D'Souza, R. M.; Krapivsky, P. L.; Moore, C. - In: The European Physical Journal B - Condensed Matter and … 59 (2007) 4, pp. 535-543

The “power of choice” has been shown to radically alter the behavior of a number of randomized algorithms. Here we explore the effects of choice on models of random tree growth. In our models each new node has k randomly chosen contacts, where k 1 is a constant. It then attaches to...

Nonlinear mean field Fokker-Planck equations. Application to the chemotaxis of biological populations

Chavanis, P. H. - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 2, pp. 179-208

We study a general class of nonlinear mean field Fokker-Planck equations in relation with an effective generalized thermodynamical (E.G.T.) formalism. We show that these equations describe several physical systems such as: chemotaxis of bacterial populations, Bose-Einstein condensation in the...
