Bose-Einstein-condensed atoms in toroidal traps

Jackson, A. D. and Kavoulakis, Georgios LU (2006) In Physical Review A (Atomic, Molecular and Optical Physics) 74(6).
Abstract
We consider Bose-Einstein-condensed atoms confined in a toroidal trap. Under conditions of one-dimensional behavior, the density distribution of the atoms may be exponentially localized or delocalized, even for very small variations in the trapping potential along the torus. For similar reasons, small irregularities of the trap may also have a very pronounced effect on the density of the cloud. The excitation spectrum is also affected by the presence of some spatially varying potential and/or irregularities in the trap.
