Mixtures of Bose gases confined in concentrically coupled annular traps
arXiv:0911.2355 · doi:10.1103/PhysRevA.81.013630
Abstract
A two-component Bose-Einstein condensate confined in an axially-symmetric potential with two local minima, resembling two concentric annular traps, is investigated. The system shows a number of quantum phase transitions that result from the competition between phase coexistence, and radial/azimuthal phase separation. The ground-state phase diagram, as well as the rotational properties, including the (meta)stability of currents in this system, are analysed.
