Low-density, one-dimensional quantum gases in a split trap
Th. Busch, G. Huyet
We investigate degenerate quantum gases in one dimension trapped in a harmonic potential that is split in the centre by a pointlike potential. Since the single particle eigenfuncti…
Bose-Einstein condensates in traps of time-dependent topology
Th. Busch, J. R. Anglin, W. H. Zurek
Superfluid phenomena can be explained in terms of the topologies of the order parameter and of the confining vessel. For example, currents in a toroidal vessel can be characterized…
Instabilities of wave function monopoles in Bose-Einstein condensates
Th. Busch, J. R. Anglin
We present analytic and numerical results for a class of monopole solutions to the two-component Gross-Pitaevski equation for a two-species Bose condensate in an effectively two-di…
Mossbauer effect for dark solitons in Bose-Einstein condensates
Th. Busch, J. R. Anglin
We show that the energetic instability of dark solitons is associated with particle-like motion, and present a simple equation of motion, based on the Mössbauer effect, for dark so…
Stability and collective excitations of a two-component Bose-condensed gas: a moment approach
Th. Busch, J. I. Cirac, V. M. Perez-Garcia +1
The dynamics of a two-component dilute Bose gas of atoms at zero temperature is described in the mean field approximation by a two-component Gross-Pitaevskii Equation. We solve thi…
