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…
Rotational and vibrational spectra of quantum rings
M. Koskinen, M. Manninen, B. Mottelson +1
One can confine the two-dimensional electron gas in semiconductor heterostructures electrostatically or by etching techniques such that a small electron island is formed. These man…
