The absence of fragmentation in Bose-Einstein condensates
A. D. Jackson, G. M. Kavoulakis, M. Magiropoulos
A Bose-Einstein condensate produced by a Hamiltonian which is rotationally or translationally symmetric is fragmented as a direct result of these symmetries. A corresponding mean-f…
Stability of persistent currents in a Bose-Einstein condensate confined in a toroidal trap
M. Ogren, G. M. Kavoulakis
Motivated by recent experiments in Bose-Einstein condensed atoms that have been confined in toroidal traps, we examine the stability of persistent currents in such systems. We inve…
Metastability of persistent currents in trapped gases of atoms
K. Karkkainen, J. Christensson, G. Reinisch +2
We examine the conditions that give rise to metastable, persistent currents in a trapped Bose-Einstein condensate. A necessary condition for the stability of persistent currents is…
Persistent currents in a Bose-Einstein condensate in the presence of disorder
M. Ogren, G. M. Kavoulakis
We examine bosonic atoms that are confined in a toroidal, quasi-one-dimensional trap, subjected to a random potential. The resulting inhomogeneous atomic density is smoothened for…
Stability of the solutions of the Gross-Pitaevskii equation
A. D. Jackson, G. M. Kavoulakis, E. Lundh
We examine the static and dynamic stability of the solutions of the Gross-Pitaevskii equation and demonstrate the intimate connection between them. All salient features related to…
Solitary waves in elongated clouds of strongly-interacting bosons
M. Ogren, G. M. Kavoulakis, A. D. Jackson
We examine the propagation of solitary waves in elongated clouds of trapped bosonic atoms as the confinement, the strength of the interatomic interaction, and the atom density are…
