One-dimensional classical diffusion in a random force field with weakly concentrated absorbers
A one-dimensional model of classical diffusion in a random force field with a weak concentration ρ of absorbers is studied. The force field is taken as a Gaussian white noise with 〈φ(x)〉 = 0 and 〈φ(x)φ(x)〉 = g δ(x− x′). Our analysis relies on the relation between the FokkerPlanck operator and a quantum Hamiltonian in which absorption leads to breaking of supersymmetry. Using a Lifshits argument...
متن کاملOne-Dimensional Diffusion in a Semi-Infinite Poisson Random Force
We consider the one-dimensional diffusion of a particle on a semiinfinite line and in a piecewise linear random potential. We first present a new formalism which yields an analytical expression for the Green function of the Fokker-Planck equation, valid for any deterministic construction of the potential profile. The force is then taken to be an asymmetric dichotomic process. Solving the corres...
متن کاملDiffusion in a weakly random Hamiltonian flow
We consider the motion of a particle governed by a weakly random Hamiltonian flow. We identify temporal and spatial scales on which the particle trajectory converges to a spatial Brownian motion. The main technical issue in the proof is to obtain error estimates for the convergence of the solution of the stochastic acceleration problem to a momentum diffusion. We also apply our results to the s...
متن کاملOne Dimensional Diffusion in an Asymmetric Random Environment
According to a theorem of S. Schumacher, for a diffusion X in an environment determined by a stable process that belongs to an appropriate class and has index a, it holds that Xt/(log t) converges in distribution as t → ∞ to a random variable having an explicit description in terms of the environment. We compute the density of this random variable in the case the stable process is spectrally on...
متن کاملDiffusion in One Dimensional Random Medium and Hyperbolic Brownian Motion
Classical diffusion in a random medium involves an exponential functional of Brownian motion. This functional also appears in the study of Brownian diffusion on a Riemann surface of constant negative curvature. We analyse in detail this relationship and study various distributions using stochastic calculus and functional integration.
