Dimensional reduction in Bose-Einstein condensed clouds of atoms confined in tight potentials of any geometry and any interaction strength
P. Sandin, M. Ögren, M. Gulliksson +3
Motivated by numerous experiments on Bose-Einstein condensed atoms which have been performed in tight trapping potentials of various geometries (elongated and/or toroidal/annular),…

Vortices in Bose-Einstein condensates - finite-size effects and the thermodynamic limit
J. C. Cremon, G. M. Kavoulakis, B. R. Mottelson +1
For a weakly-interacting Bose gas rotating in a harmonic trap we relate the yrast states of small systems (that can be treated exactly) to the thermodynamic limit (derived within t…
