The Gross-Pitaevskii equations and beyond for inhomogeneous condensed bosons
G. G. N. Angilella, S. Bartalini, F. S. Cataliotti +3
A simple derivation of the static Gross-Pitaevskii (GP) equation is given from an energy variational principle. The result is then generalized heuristically to the time-dependent G…
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…
A Novel Mechanism for Superfluidity Breakdown in Weakly Coupled Bose-Einstein Condensates
F. S. Cataliotti, L. Fallani, F. Ferlaino +7
This paper has been withdrawn by the authors. The authors have now written two separate papers, one theoretical (A. Smerzi, A. Trombettoni, P. G. Kevrekidis, and A. R. Bishop Phys.…
