Momentum transferred to a trapped Bose-Einstein condensate by stimulated light scattering
A. Brunello, F. Dalfovo, L. Pitaevskii +2
The response of a trapped Bose-Einstein condensed gas to a density perturbation generated by a two-photon Bragg pulse is investigated by solving the time-dependent Gross-Pitaevskii…

How to measure the Bogoliubov quasiparticle amplitudes in a trapped condensate
A. Brunello, F. Dalfovo, L. Pitaevskii +1
We propose an experiment, based on two consecutive Bragg pulses, to measure the momentum distribution of quasiparticle excitations in a trapped Bose gas at low temperature. With th…
