Damping rates of the atomic velocity in Sisyphus cooling
Laurent Sanchez-Palencia, Michele Schiavoni, Francois-Regis Carminati +2
We present a theoretical and experimental study of the damping process of the atomic velocity in Sisyphus cooling. The relaxation rates of the atomic kinetic temperature are determ…
Phase-control of directed diffusion in a symmetric optical lattice
Michele Schiavoni, Laurent Sanchez-Palencia, Ferruccio Renzoni +1
We demonstrate the phenomenon of directed diffusion in a symmetric periodic potential. This has been realized with cold atoms in a one-dimensional dissipative optical lattice. The…
Rayleigh Scattering and Atomic Dynamics in Dissipative Optical Lattices
Francois-Regis Carminati, Laurent Sanchez-Palencia, Michele Schiavoni +2
We investigate Rayleigh scattering in dissipative optical lattices. In particular, following recent proposals (S. Guibal {\it et al}, Phys. Rev. Lett. {\bf 78}, 4709 (1997); C. Jur…
Dark propagation modes in optical lattices
Michele Schiavoni, Laurent Sanchez-Palencia, Francois-Regis Carminati +2
We examine the stimulated light scattering onto the propagation modes of a dissipative optical lattice. We show that two different pump-probe configurations may lead to the excitat…
Stochastic resonance in periodic potentials: realization in a dissipative optical lattice
Michele Schiavoni, Francois-Regis Carminati, Laurent Sanchez-Palencia +2
We have observed the phenomenon of stochastic resonance on the Brillouin propagation modes of a dissipative optical lattice. Such a mode has been excited by applying a moving poten…
Brillouin propagation modes in optical lattices: interpretation in terms of nonconventional stochastic resonance
L. Sanchez-Palencia, F. -R. Carminati, M. Schiavoni +2
We report the first direct observation of Brillouin-like propagation modes in a dissipative periodic optical lattice. This has been done by observing, in both theoretical and exper…
