Non-equilibrium fluctuations in a driven stochastic Lorentz gas #
We study the stationary state of a one-dimensional kinetic model where a
probe particle is driven by an external field E and collides, elastically
or inelastically, with a bath of particles at temperature T.
In particular, we focus on the stationary distribution of the velocity of
the particle, and on the study of the fluctuations of the stochastic
entropy and of the work done by the field.
