Rotational response of two-component Bose-Einstein condensates in ring traps.

Halkyard, P. L. and Jones, M. P. A. and Gardiner, S. A. (2010) 'Rotational response of two-component Bose-Einstein condensates in ring traps.', Physical review A., 81 (6).

Abstract

We consider a two-component Bose-Einstein condensate in a ring trap in a rotating frame and show how to determine the response of such a configuration to being in a rotating frame via accumulation of a Sagnac phase. This may be accomplished through either population oscillations or the motion of spatial-density fringes. We explicitly include the effect of interactions via a mean-field description and study the fidelity of the dynamics relative to an ideal configuration.
