    "abstract": "We report the first direct observation of Brillouin-like propagation modes in\na dissipative periodic optical lattice. This has been done by observing, in\nboth theoretical and experimental work, a resonant behaviour of the spatial\ndiffusion coefficient in the direction corresponding to the propagation mode\nwith the phase velocity of the moving intensity modulation used to excite these\npropagation modes. Furthermore, we show theoretically that the amplitude of the\nBrillouin mode is a nonmonotonic function of the strength of the noise\ncorresponding to the optical pumping, and discuss this behaviour in terms of\nnonconventional stochastic resonance.",
