Abstract
We study the one-dimensional diffusion process which takes place between two reflecting boundaries and which is acted upon by a time-dependent and spatially-constant force. The assumed force possesses both the harmonically oscillating and the constant component. Using techniques presented in the paper [1] we derive the set of integral equations whose comprise the Green function for our diffusion process. In the later part we focus on the time-asymptotic stationary regime of considered non-equilibrium process. Some of its time-asymptotic characteristics, e.g. time-averaged and time-asymptotic probability density of the particle coordinate, exhibit nontrivial features.
