Towards light induced spin-orbit coupling for ultra-cold neutral atoms — •Sebastian Bode, Felix Kösel, Holger Ahlers, Katerine Posso Trujillo, Naceur Gaaloul, and Ernst Rasel — IQ Universität Hannover

We present the status of our experiment for engineering 2D spin-orbit coupling [1] of a neutral Rubidium Bose-Einstein condensate. Using 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.
