A note on quenched moderate deviations for Sinai's random walk in random environment
ESAIM: Probability and Statistics, Tome 8 (2004), pp. 56-65.

We consider the continuous time, one-dimensional random walk in random environment in Sinai’s regime. We show that the probability for the particle to be, at time t and in a typical environment, at a distance larger than t a (0<a<1) from its initial position, is exp{- Const ·t a /[(1-a)lnt](1+o(1))}.
