The effective diffusion constant of stochastic processes with spatially periodic noise
Stefano Giordano, Ralf Blossey
We discuss the effective diffusion constant for stochastic processes with spatially-dependent noise. Starting from a stochastic process given by a Langevin equation,…

Short-time expansion of one-dimensional Fokker-Planck equations with heterogeneous diffusion
Tom Dupont, Stefano Giordano, Fabrizio Cleri +1
We formulate a short-time expansion for one-dimensional Fokker-Planck equations with spatially dependent diffusion coefficients, derived from stochastic processes with Gaussian whi…
