Query: Dynamical random walk on the integers with a drift   In this note we study dynamical random walks (DRW) with internal states. We
consider a particle which performs a dynamical random walk on $\mathbb{Z}$ and
whose local dynamics is given by expanding maps. We provide sufficient
conditions for the position of the particle $z_n$ to satisfy the Central Limit
Theorem.
