Tunnelling-induced Collapse of an Atomic Bose-Einstein Condensate in a Double-well Potential (2004)

Author(s): Sakellari E, Proukakis NP, Adams CS

    Abstract: The stability of a low-temperature Bose–Einstein condensate with attractive interactions in one- and three-dimensional double-well potentials is discussed. In particular, the tunnelling dynamics of a condensate under the influence of a time-dependent potential gradient is investigated. The condensate is shown to collapse at a critical potential gradient which corresponds to a critical number of atoms in one of the two wells. The sensitivity of this tunnelling-induced collapse could provide a useful tool in the study of condensates with attractive interactions.
