    "abstract": "We theoretically study the influence of the noise strength on the excitation\nof the Brillouin propagation modes in a dissipative optical lattice. We show\nthat the excitation has a resonant behavior for a specific amount of noise\ncorresponding to the precise synchronization of the Hamiltonian motion on the\noptical potential surfaces and the dissipative effects associated with optical\npumping in the lattice. This corresponds to the phenomenon of stochastic\nresonance. Our results are obtained by numerical simulations and correspond to\nthe analysis of microscopic quantities (atomic spatial distributions) as well\nas macroscopic quantities (enhancement of spatial diffusion and pump-probe\nspectra). We also present a simple analytical model in excellent agreement with\nthe simulations.",
