摘要

We report the results of a novel simulation for a single particle driven by a constructed distribution of non-Gaussian fluctuations. At each time step of the simulation, a pre-assembled look-up table of non-Gaussian fluctuations is used to "kick" the mobile tracer particle in a random direction in a 2D plane. The interaction between the bath and the tracer also includes a velocity-dependent viscous term that dissipates a portion of the energy gained in each kick of the particle. This simple code
