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…
Rabi oscillations of 2D electrons under ultrafast intersubband excitation
D. McPeake, F. T. Vasko, E. P. O'Reilly
We investigate coherent nonlinear dynamics of 2D electrons under ultrafast intersubband excitation by mid-IR pulses. We include the effects of relaxation and dephasing, both homoge…
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…
Gyroscopic motion of superfluid trapped atomic condensates
Halvor Moll Nilsen, Dermot McPeake, J F McCann
The gyroscopic motion of a trapped Bose gas containing a vortex is studied. We model the system as a classical top, as a superposition of coherent hydrodynamic states, by solution…
Collective excitations of trapped Bose condensates in the energy and time domains
Dermot McPeake, Halvor Moll Nilsen, J. F. McCann
A time-dependent method for calculating the collective excitation frequencies and densities of a trapped, inhomogeneous Bose-Einstein condensate with circulation is presented. The…
