Abstract

Starting from the equations of Gross–Pitaevskii for the order parameter we investigate the collective modes of a trapped Bose-condensed gas. These excitations are analogous to the propagation of phonons in homogeneous Bose superfluids. The coupling between the monopole and quadrupole vibrations in a deformed trap is explicitly investigated and the predictions are successfully compared with recent experimental data.
