Non-equilibrium dynamics of the piston in the Szilard engine

open access: yes, 2018
We consider a Szilard engine in one dimension, consisting of a single particle of mass $m$, moving between a piston of mass $M$, and a heat reservoir at temperature $T$. In addition to an external force, the piston experiences repeated elastic collisions
