Gauge fields in multi-level atoms: a tutorial — •Ian B. Spielman — University of Maryland, College Park, MD, USA — National Institute of Standards and Technology, Gaithersburg, MD, USA

We use Raman lasers to induce artificial gauge fields or spin-orbit coupling in the F=1 electronic ground state manifold of rubidium-87, I will describe this physics in the language of the Berry's phase. With this backdrop, I will explain our recent experiments engineering a two-dimensional magnetic lattice in an elongated strip geometry, with effective per-plaquette flux about 4/3 times the flux quanta where the lattice's long direction consisted of the sites of an optical lattice and its narrow direction consisted of the internal atomic spin states: a synthetic dimension.
