Summary: We prove that two seemingly different models of random walk in random environment are generically quite close to one another. One model comes from statistical physics, and describes the behavior of a randomly charged random polymer. The other model comes from probability theory, and was originally designed to describe a large family of asymptotically self-similar processes that have stationary increments.
