Tunnelling dynamics of a Bose-Einstein condensate in a four-well loop-shaped system
- Laboratoire Pierre Aigrain, Ecole Normale Superieure, 24 rue Lhomond, 75005 Paris (France)
We investigated the tunnelling dynamics of a zero-temperature Bose-Einstein condensate in configuration of four potential wells arranged in a loop. We found three interesting dynamic regimes: (a) flows of matter with small amplitude (b) steady flow, and (c) forced flow of matter for large amplitudes. The regime of quantum self-confinement has been studied and a new variant of it has been found for this system.
