Large deviations for a zero mean asymmetric
zero range process in random media.

ABSTRACT. We consider an asymmetric zero range process in infinite volume with
zero mean and random jump rates starting from equilibrium.
We investigate the large deviations from the hydrodynamical limit of the
empirical distribution of particles and prove an upper and a lower
bound for the large deviation principle. Our main argument is based
on a super-exponential estimate in infinite volume. For this we extend
to our case a method developed by Kipnis & al. (1989) and Benois & al.
(1995).
