Description:
Author(s): Xiaopeng Li, Erhai Zhao, and W. Vincent Liu Motivated by the recent experiment on p -orbital-band bosons in optical lattices, we study theoretically the quantum phases of Mott insulator and superfluidity in two dimensions. The system features a superfluid phase with transversely staggered orbital current at weak interaction and a Mott insulato... [Phys. Rev. A 83, 063626] Published Mon Jun 20, 2011
