Multi-Gaussian modes of diffusion in a quenched random medium.
نویسندگان
چکیده
We have studied a model of a random walk in a quenched random environment. In addition to featuring anomalous diffusion and localization, for special regimes of disorder parameters the particle density decomposes into multi-Gaussian structure while its cumulative distribution is normal. We explain the observed fine structure of the density and point out its significance to experiments.

Dynamics of a polymer in a quenched random medium: A Monte Carlo investigation
– We use an off lattice bead spring model of a self avoiding polymer chain immersed in a 3-dimensional quenched random medium to study chain dynamics by means of a Monte Carlo (MC) simulation. The chain center of mass mean-squared displacement as a function of time reveals two crossovers which depend both on chain length N and on the degree of Gaussian disorder ∆. The first one from normal to a...
متن کاملPolymer Diffusion in Quenched Disorder: A Renormalization Group Approach
We study the diffusion of polymers through quenched short-range correlated random media by renormalization group (RG) methods, which allow us to derive universal predictions in the limit of long chains and weak disorder. We take local quenched random potentials with second moment v and the excludedvolume interaction u of the chain segments into account. We show that our model contains the relev...
متن کاملExtremal-point densities of interface fluctuations in a quenched random medium
We give a number of exact, analytical results for the stochastic dynamics of the density of local extrema (minima and maxima) of linear Langevin equations and solid-on-solid lattice growth models driven by spatially quenched random noise. Such models can describe nonequilibrium surface fluctuations in a spatially quenched random medium, diffusion in a random catalytic environment, and polymers ...
متن کاملQuenched large deviations for multiscale diffusion processes in random environments*
We consider multiple time scales systems of stochastic differential equations with small noise in random environments. We prove a quenched large deviations principle with explicit characterization of the action functional. The random medium is assumed to be stationary and ergodic. In the course of the proof we also prove related quenched ergodic theorems for controlled diffusion processes in ra...
متن کاملS ep 2 00 1 Localization of polymers in a finite medium with fixed random obstacles
In this paper we investigate the conformation statistics of a Gaussian chain embedded in a medium of finite size, in the presence of quenched random obstacles. The similarities and differences between the case of random obstacles and the case of a Gaussian random potential are elucidated. The connection with the density of states of electrons in a metal with random repulsive impurities of finit...
