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 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 analyzed.
