Transport dynamics of a $^{87}$Rb BEC in an artificial magnetic field

ORAL

Abstract

Despite the electrical neutrality of ultracold quantum gases, the combination of far-detuned Raman lasers and spatially-dependent Zeeman energies can be used to effect a Lorentz force for ultracold atoms [1]. The transport dynamics of a Bose-Einstein condensate (BEC) in an artificial magnetic field are similar to those in a solid, displaying, for example, the Hall effect. Using external forces to drive a mass current, we study transport in a $^{87}$Rb BEC as a function of the applied artificial magnetic field and explore the resulting Hall coefficients. \\[4pt] [1] Y.-J.
