Phys. Rev. Lett. 96, 190401 (2006) [4 pages]Quantum Magnetism with Multicomponent Dipolar Molecules in an Optical LatticeReceived 13 January 2006; published 16 May 2006 We consider bosonic dipolar molecules in an optical lattice prepared in a mixture of different rotational states. The 1/r3 interaction between molecules for this system is produced by exchanging a quantum of angular momentum between two molecules. We show that the Mott states of such systems have a large variety of quantum phases characterized by dipolar orderings including a state with an ordering wave vector that can be changed by tilting the lattice. As the Mott insulating phase is melted, we also describe several exotic superfluid phases that will occur. © 2006 The American Physical Society URL:
