Abstract

We report on the realization of a novel rotating beam trap to investigate the superfluidity properties of Bose-Einstein condensates with different quanta of angular momentum. This has been achieved by scanning a red detuned focused beam trap using a 2-axis AOM while compensating for varying diffraction efficiencies using a synchronized AM modulation. Using this set up allows the creation of different ring diameters as well as adding different amounts of angular momentum to the Bose-Einstein condensate.
