On the theory of transport phenomena in ferrofluids. Effect of chain-like aggregates

Zubarev, A. Yu. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 1, pp. 72-78

The paper deals with the theoretical study of the effect of chain-like aggregates on diffusion and magnetophoretic transport in ferrofluids. Analysis shows that the appearance of the chains leads to a strong anisotropy of the diffusion transport–the coefficient of diffusion in the direction of...

BML model on non-orientable surfaces

Cámpora, Daniel; de la Torre, Jaime; Vázquez, García; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3290-3298

Two-dimensional Biham–Middleton–Levine traffic model on a N×N square lattice embedded on a Klein bottle and a projective plane is investigated by computer simulations. The behavior of the model with these boundary conditions is compared with the model under toroidal boundary conditions. Our...

Periodic states, local effects and coexistence in the BML traffic jam model

Linesch, Nicholas J.; D’Souza, Raissa M. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 24, pp. 6170-6176

The Biham–Middleton–Levine (BML) model is simple lattice model of traffic flow, self-organization and jamming. Rather than a sharp phase transition between free-flow and jammed, it was recently shown that there is a region where stable intermediate states exist, with details dependent on the...

Stochastic resonance and Brownian ratchets

Fendrik, A.J.; Romanelli, L.; Perazzo, R.P.J. - In: Physica A: Statistical Mechanics and its Applications 359 (2006) C, pp. 75-84

We discuss the connections between Brownian ratchets (BR) and stochastic resonance (SR). We consider a periodic potential energy landscape with no left–right symmetry that is driven by an external force which can be derived from a potential that is periodic both in time and space. We show that...
