Phys. Rev. Lett. 96, 180407 (2006) [4 pages]High-Field Fractional Quantum Hall Effect in Optical Lattices
Received 26 December 2005; published 12 May 2006
We consider interacting bosonic atoms in an optical lattice subject to a large simulated magnetic field. We develop a model similar to a bilayer fractional quantum Hall system valid near simple rational numbers of magnetic flux quanta per lattice cell. Then we calculate its ground state, magnetic lengths, fractional fillings, and find unexpected sign changes in the Hall current. Finally we study methods for detecting these novel features via shot noise and Hall current measurements. ©2006 The American Physical Society
