Superfluid toroidal currents in atomic condensates
Eileen Nugent, Dermot McPeake, J F McCann
The dynamics of toroidal condensates in the presence of condensate flow and dipole perturbation have been investigated. The Bogoliubov spectrum of condensate is calculated for an o…

Wave mixing of hybrid Bogoliubov modes in a Bose-Einstein condensate
Dermot McPeake, J F McCann
Mode-mixing of coherent excitations of a trapped Bose-Einstein condensate is modelled using the Bogoliubov approximation. Hybridization of the modes of the breather () and sur…
