A smooth, holographically generated ring trap for the investigation of superfluidity in ultracold atoms

Abstract

We discuss the suitability of holographically generated optical potentials\nfor the investigation of superfluidity in ultracold atoms. By using a spatial\nlight modulator and a feedback enabled algorithm we generate a smooth ring with\nvariable bright regions that can be dynamically rotated to stir ultracold atoms\nand induce superflow. We also comment on its future integration into a cold\natoms experiment.\n
