Observation of dynamical instability for a Bose-Einstein condensate in a moving 1D optical lattice
L. Fallani, L. De Sarlo, J. E. Lye +4
We have experimentally studied the unstable dynamics of a harmonically trapped Bose-Einstein condensate loaded into a 1D moving optical lattice. The lifetime of the condensate in s…
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…
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…
Collective excitations of a trapped Bose-Einstein condensate in the presence of a 1D optical lattice
C. Fort, F. S. Cataliotti, L. Fallani +3
We study low-lying collective modes of a horizontally elongated 87Rb condensate produced in a 3D magnetic harmonic trap with the addition of a 1D periodic potential which is provid…
