dc.descriptionPaper included in "Proceedings of the VIII Latin American Workshop on Nonlinear Phenomena" (Salvador, Bahia, Brazil, 28 September-03 October 2003, edited by R.F.S. Andrade, S.R.T. Pinho and S.R.A. Salinas).-
dc.description.abstractWe present a one-dimensional model for diffusion in a fluctuating lattice; that is a lattice which can be in two or more states. Transitions between the lattice states are induced by a combination of two processes: one periodic deterministic and the other stochastic. We study the dynamics of a system of particles moving in that medium, and characterize the problem from different points of view: mean first passage time (MFPT), probability of return to a given site (P_{s_0}), and the total length displacement or number of visited lattice sites (Λ). We observe a double resonant activation-like phenomenon when we plot the MFPT and P_{s_0} as functions of the intensity of the transition rate stochastic component.en_US
