Brillouin propagation modes in optical lattices: interpretation in terms of nonconventional stochastic resonance.
Laurent Sanchez-Palencia,Francois-Regis Carminati,Michele Schiavoni,Ferrucio Renzoni,Gilbert Grynberg +4 more
TL;DR: It is shown theoretically that the amplitude of the Brillouin mode is a nonmonotonic function of the strength of the noise corresponding to the optical pumping, and discussed in terms of nonconventional stochastic resonance.
Stochastic resonance in periodic potentials: Realization in a dissipative optical lattice
Michele Schiavoni,Francois-Regis Carminati,Laurent Sanchez-Palencia,Ferruccio Renzoni,G. Grynberg +4 more
TL;DR: In this paper, the authors have observed the phenomenon of stochastic resonance on the Brillouin propagation modes of a dissipative optical lattice, which is characterized by the center-of-mass (CM) velocity of the atomic cloud.

Rayleigh scattering and atomic dynamics in dissipative optical lattices.
Francois-Regis Carminati,Laurent Sanchez-Palencia,Michele Schiavoni,Ferruccio Renzoni,Gilbert Grynberg +4 more
TL;DR: It turns out that the Rayleigh line is instead a measure of the cooling rate, while spatial diffusion contributes to the scattering spectrum with a much broader resonance.
Temperature and spatial diffusion of atoms cooled in a 3D lin$\perp$lin bright optical lattice
Francois-Regis Carminati,Michele Schiavoni,Laurent Sanchez-Palencia,Ferruccio Renzoni,G. Grynberg +4 more
TL;DR: In this paper, a detailed experimental study of a three-dimensional lin$\perp$lin bright optical lattice is presented, where measurements of the atomic temperature and spatial diffusion coefficients are reported for different angles between the lattice beams.

Pump-probe spectroscopy of atoms cooled in a 3D lin⊥lin optical lattice
TL;DR: In this article, a pump-probe spectroscopy of atoms cooled in a 3D lin⊥lin optical lattice is described. And the results are supported by transport-spectroscopy measurements, which allow to distinguish contributions to the light scattering from propagating and non-propagating atoms.
