We investigate a celebrated problem of one dimensional tight binding model inthe presence of disorder leading to Anderson localization from a novelperspective. A binary disorder is assumed to be created by immobile heavyparticles for the motion of the lighter, mobile species in the limit of nointeraction between mobile particles. Fast periodic modulations of interspeciesinteractions allow us to produce an effective model with small diagonal andlarge off-diagonal disorder unexplored in cold atoms experiments. We present anexpression for an approximate Anderson localization length and verify theexistence of the well known extended resonant mode and analyze the influence ofnonzero next-nearest neighbor hopping terms. We point out that periodicmodulation of interaction allow disorder to work as a tunable band-pass filterfor momenta.
