Spin-Orbit Driven Transitions Between Mott Insulators and Finite Momentum Superfluids of Bosons in Optical Lattices [link]Website  abstract   bibtex   
Synthetic spin-orbit coupling in ultracold atomic gases can be taken to extremes rarely found in solids. We study a two dimensional Hubbard model of bosons in an optical lattice in the presence of spin-orbit coupling strong enough to drive direct transitions from Mott insulators to superfluids. Here we find phase-modulated superfluids with finite momentum that are generated entirely by spin-orbit coupling. Transitions between different superfluids are also found to be first-order. We investigate the rich periodic structure of the phases of the superfluids, which may be directly probed using time-of-flight imaging of the spin-dependent momentum distribution.
