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...

Exactly solvable reaction diffusion models on a Cayley tree

Matin, L. F.; Aghamohammadi, A.; Khorrami, M. - In: The European Physical Journal B - Condensed Matter and … 56 (2007) 3, pp. 243-246

The most general reaction-diffusion model on a Cayley tree with nearest-neighbor interactions is introduced, which can be solved exactly through the empty-interval method. The stationary solutions of such models, as well as their dynamics, are discussed. Concerning the dynamics, the spectrum of...

A quasi-elastic regime for vibrated granular gases

Aumaître, S.; Alastuey, A.; Fauve, S. - In: The European Physical Journal B - Condensed Matter and … 54 (2006) 2, pp. 263-266

Using simple scaling arguments and two-dimensional numerical simulations of a granular gas excited by vibrating one of the container boundaries, we study a double limit of small 1-r and large L, where r is the restitution coefficient and L the size of the container. We show that if the particle...
