Shell structure and pairing for interacting fermions in a trap
Henning Heiselberg, Ben Mottelson
The shell structures for weakly interacting fermions in harmonic oscillator traps at zero temperature undergo several transitions depending on the number of particles in the trap a…
Low energy Collective Modes of a Superfluid Trapped atomic Fermi Gas
G. M. Bruun, B. R. Mottelson
We consider the low energy collective mode spectrum of a superfluid Fermi gas in a spherical trap in the collisionless regime. Using a self-consistent random-phase approximation, t…
Low-lying excitations of a trapped rotating Bose-Einstein condensate
G. M. Kavoulakis, B. Mottelson, S. M. Reimann
We investigate the low-lying excitations of a weakly-interacting, harmonically-trapped Bose-Einstein condensed gas under rotation, in the limit where the angular mometum of the…
Weakly Interacting Bose-Einstein Condensates Under Rotation: Mean-field versus Exact Solutions
A. D. Jackson, G. M. Kavoulakis, B. Mottelson +1
We consider a weakly-interacting, harmonically-trapped Bose-Einstein condensed gas under rotation and investigate the connection between the energies obtained from mean-field calcu…
Weakly-interacting Bose-Einstein condensates under rotation
G. M. Kavoulakis, B. Mottelson, C. J. Pethick
We investigate the ground and low excited states of a rotating, weakly interacting Bose-Einstein condensed gas in a harmonic trap for a given angular momentum. Analytical results i…
