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…
Bright solitary waves in a Bose-Einstein condensate and their interactions
K. Karkkainen, A. D. Jackson, G. M. Kavoulakis
We examine the dynamics of two bright solitary waves with a negative nonlinear term. The observed repulsion between two solitary waves -- when these are in an antisymmetric combina…
Manipulating Bose-Einstein condensed atoms in toroidal traps
A. D. Jackson, G. M. Kavoulakis
We consider Bose-Einstein condensed atoms confined in a toroidal trap. We demonstrate that under conditions of one-dimensional behavior, the density distribution of the atoms may b…
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…
Multi-channel scattering and Feshbach resonances: Effective theory, phenomenology, and many-body effects
G. M. Bruun, A. D. Jackson, E. E. Kolomeitsev
A low energy effective theory based on a microscopic multi-channel description of the atom-atom interaction is derived for the scattering of alkali atoms in different hyperfine sta…
Hysteresis and persistent currents in a rotating Bose-Einstein condensate with anharmonic confinement
A. D. Jackson, G. M. Kavoulakis
We examine a Bose-Einstein condensate of atoms that rotates in a quadratic-plus-quartic potential. It is shown that states of different circulation can be metastable. As a result,…
