Session A19 - Patterns and Dynamics.
ORAL session, Monday morning, March 22
512BF, Palais des Congres
Using mean-field and numerical methods, we analyze the steady-state behavior of totally asymmetric simple exclusion processes (TASEPs) containing periodically varying movement rates. In our models particles at a majority sites hop to the right with rate p_1, while particles occupying a periodically arranged set of sites move to the right at rate p_2. While exact solutions for the steady-state particle currents and densities are not found, the mean field results show good agreement with data derived from extensive Monte-Carlo simulations.
