Biased random walks on a lattice: exact numerical method to study the effect of alternating fields in disordered and asymmetric systems of obstacles.

Abstract

The migration of a particle in a system of obstacles under the action of an external field is often modeled using lattice Monte Carlo algorithms. For example, such simulation methods have been used to study the electrophoresis of charged molecules in sieving gels and the separation of particles using ratchet systems. In the case of constant fields or low… (More)
