Controlled generation of coherent matter currents using a periodic driving field

We study the effect of a strong, oscillating driving field on the dynamics of ultracold boson held in an optical lattice. Modeling the system as a Bose-Hubbard model, we show how the driving field can be used to produce and maintain a coherent atomic current by controlling the phase of the intersite...
