Optical Flux Lattices for Two-Photon Dressed States

Understand

We describe a simple scheme by which "optical flux lattices" can be implemented in ultracold atomic gases using two-photon dressed states.

• This scheme can be applied, for example, to the ground state hyperfine levels of commonly used atomic species.
• The resulting flux lattices simulate a magnetic field with high mean flux density, and have low energy bands analogous to the lowest Landau level.
• We show that in practical cases the atomic motion significantly deviates from the adiabatic following of one dressed state, and that this can lead to significant interactions even for fermions occupying a single band.
