Phys. Rev. A 76, 043601 (2007) [11 pages]Hall effects in Bose-Einstein condensates in a rotating optical latticeReceived 22 May 2007; published 1 October 2007 Using linear response theory, we demonstrate fractional quantum Hall features in a rotating Bose-Einstein condensate in a corotating two-dimensional optical lattice. The corotating lattice and trap potential allow for an effective magnetic field and compensation of the centrifugal potential. Fractional quantum Hall features in the current response are seen for the single-particle system and for a few strongly interacting many-particle systems. © 2007 The American Physical Society URL:
