Superfluid current disruption in a chain of weakly coupled Bose-Einstein Condensates
F. S. Cataliotti, L. Fallani, F. Ferlaino +3
We report the experimental observation of the disruption of the superfluid atomic current flowing through an array of weakly linked Bose-Einstein condensates. The condensates are t…
Polarization phase gate with a tripod atomic system
S. Rebic, D. Vitali, C. Ottaviani +4
We analyze the nonlinear optical response of a four-level atomic system driven into a tripod configuration. The large cross-Kerr nonlinearities that occurr in such a system are sho…
Superradiant light scattering from a moving Bose-Einstein condensate
R. Bonifacio, F. S. Cataliotti, M. Cola +4
We investigate the interaction of a moving BEC with a far detuned laser beam. Superradiant Rayleigh scattering arises from the spontaneous formation of a matter-wave grating due to…
Optically-induced lensing effect on a Bose-Einstein condensate expanding in a moving lattice
L. Fallani, F. S. Cataliotti, J. Catani +4
We report the experimental observation of a lensing effect on a Bose-Einstein condensate expanding in a moving 1D optical lattice. The effect of the periodic potential can be descr…
Polarization qubit phase gate in driven atomic media
Carlo Ottaviani, David Vitali, Maurizio Artoni +2
We present here an all--optical scheme for the experimental realization of a quantum phase gate. It is based on the polarization degree of freedom of two travelling single photon w…
