| Research Abstract |
We study emergence of novel quantum phases and their dynamical properties in ultracold gases of atoms in an optical lattice with rotation or frustration. We consider the vortex formation of a Bose-Einstein condensates in an optical lattice and analyze the relevant experimental results done by a group of Oxford university. We also study phase structures of bosons in an optical lattice using the generalized frustrated XY model.
