Space-time nonlinear compression and three-dimensional complex trapping in normal dispersion
G. Valiulis, J. Kilius, O. Jedrkiewicz +6
In positive phase-mismatched SHG and normal dispersion, a gaussian spatio-temporal pulse transforms spontaneously into a X-pulse, underlies spatio-temporal compression and eventual…
Entanglement and squeezing in a two-mode system: theory and experiment
Vincent Josse, Aurelien Dantan, Alberto Bramati +1
We report on the generation of non separable beams produced via the interaction of a linearly polarized beam with a cloud of cold cesium atoms placed in an optical cavity. We conve…
Continuous variable entanglement using cold atoms
Vincent Josse, Aurelien Dantan, Alberto Bramati +2
We present experimental demonstration of quadrature and polarization entanglement generated via the interaction between a coherent linearly polarized field and cold atoms in a high…
Polarization squeezing with cold atoms
Vincent Josse, Aurelien Dantan, Laurent Vernac +3
We study the interaction of a nearly resonant linearly polarized laser beam with a cloud of cold cesium atoms in a high finesse optical cavity. We show theoretically and experiment…
Polarization squeezing in a four-level system
V. Josse, A. Dantan, A. Bramati +2
We present a theoretical study of an ensemble of X-like 4-level atoms placed in an optical cavity driven by a linearly polarized field. We show that the self-rotation (SR) process…
