Large Deviations for Perturbed Reflected Diffusion Processes

In this article, we establish a large deviation principle for the solutions of perturbed reflected diffusion processes. The key is to prove a uniform Freidlin-Ventzell estimates of perturbed diffusion processes.

Universal large deviations for the tagged particle in single-file motion.

We consider a gas of point particles moving in a one-dimensional channel with a hard-core interparticle interaction that prevents particle crossings--this is called single-file motion. Starting from equilibrium initial conditions we observe the motion of a tagged particle. It is well known that if the individual particle dynamics is diffusive, then the tagged particle motion is subdiffusive, wh...

Infinitely fast diffusion in single-file systems.

We have used dynamic Monte Carlo(DMC) methods and analytical techniques to analyze single-file systems for which diffusion is infinitely fast. We have simplified the master equation removing the fast reactions, and we have introduced a DMC algorithm for infinitely fast diffusion. The DMC method for fast diffusion give similar results as the standard DMC with high diffusion rates. We have invest...

Single-file diffusion in a box.

We study diffusion of (fluorescently) tagged hard-core interacting particles of finite size in a finite one-dimensional system. We find an exact analytical expression for the tagged particle probability density function using a Bethe ansatz, from which the mean square displacement is calculated. The analysis shows the existence of three regimes of drastically different behavior for short, inter...

Large Deviations for a Scalar Diffusion in Random Environment

Let ξ(u), u ∈ R be an ergodic stationary Markov chain, taking a finite number of values, and consider the diffusion process generated by the SDE dX t = b(X ε t )dt+ ε ξ ( X t /ε ) dBt with a small positive scaling parameter ε, where B = (Bt)t∈R+ is a Brownian motion, independent of ξ, and κ ≥ 0 is a fixed constant. Such model describes evolution of a particle, perturbed by a small white noise d...
