On the structure of competitive societies

Ben-Naim, E.; Vazquez, F.; Redner, S. - In: The European Physical Journal B - Condensed Matter and … 49 (2006) 4, pp. 531-538

We model the dynamics of social structure by a simple interacting particle system. The social standing of an individual agent is represented by an integer-valued fitness that changes via two offsetting processes. When two agents interact one advances: the fitter with probability p and the less...

Gravitational structure formation, the cosmological problem and statistical physics

Pietronero, L.; Labini, F. Sylos - In: The European Physical Journal B - Condensed Matter and … 50 (2006) 1, pp. 285-289

Models of structure formation in the universe postulate that matter distributions observed today in galaxy catalogs arise, through a complex non-linear dynamics, by gravitational evolution from a very uniform initial state. Dark matter plays the central role of providing the primordial density...

Modelling disorder: the cases of wetting and DNA denaturation

Ares, S.; Sánchez, A. - In: The European Physical Journal B - Condensed Matter and … 56 (2007) 3, pp. 253-258

We study the effect of the composition of the genetic sequence on the melting temperature of double stranded DNA, using some simple analytically solvable models proposed in the framework of the wetting problem. We review previous work on disordered versions of these models and solve them when...

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 …
