Towards light induced 2D spin-orbit coupling for ultra-cold neutral atoms — •Sebastian Bode, Felix Kösel, Naceur Gaaloul, Holger Ahlers, and Ernst M. Rasel — Institut für Quantenoptik Uni Hannover

Presentation of the experimental efforts we pursue towards engineering a 2D spin-orbit-coupling [1] of a neutral Rubidium Bose-Einstein condensate (BEC). Using multiple Raman transitions to couple cyclically three hyperfine Zeeman states of the atoms, an effective gauge field is predicted to be created which resembles the one occurring in spintronic systems [2]. Such an artificial interaction could be used to build advanced solid state simulators with non-Abelian character in a versatile cold-atom system. The first experimental steps realized to build a BEC machine featuring a hybrid source concept [3] are presented.
