Using Raman transitions to couple three ground states of rubidium-87 atoms, we can simulate the effects of a vector potential for ultracold atoms. In addition to demonstrating effective magnetic fields, electric fields, and spin orbit coupling, we study how the transport of a BEC is modified by the presence of the gauge potential and results in a Hall signal. Modifications to the effective mass and interactions between atoms have also been demonstrated.
