Dissipation-induced symmetry breaking in a driven optical lattice
R. Gommers, S. Bergamini, F. Renzoni
We analyze the atomic dynamics in an ac driven periodic optical potential which is symmetric in both time and space. We experimentally demonstrate that in the presence of dissipati…

Resonant activation in a nonadiabatically driven optical lattice
R. Gommers, P. Douglas, S. Bergamini +3
We demonstrate the phenomenon of resonant activation in a non-adiabatically driven dissipative optical lattice with broken time-symmetry. The resonant activation results in a reson…

A frequency-doubled, pulsed laser system for rubidium manipulation
J. Dingjan, B. Darquie, J. Beugnon +5
We have constructed a pulsed laser system for the manipulation of cold Rb atoms. The system combines optical telecommunications components and frequency doubling to generate light…
