Description
Contrary to the periodic Lorentz gas, for which Sinai and Bunimovich established the CLT, not much is know about the random case. As usual, one approach is to meaningfully simplify the problem. To do so I will consider the random Lorentz gas as a special case of a larger class of "deterministic walks in random environment" and I will put forward an idea on how to undertake the study of such problems. I will then test such an approach on some simple (but non trivial) model.
