Ring-traps on atom chips — •Anton Piccardo-Selg, James Clewett, Sonali Warriar, Gal Aviv, Lucia Hackermüller, Thomas Fernholz, and Peter Krüger — University of Nottingham, United Kingdom

Atom chips allow for almost arbitrary trapping geometries for atomic ensembles by means of magnetic, electric, optical, microwave and radio-frequency potentials. We report on the setup of a new atom chip apparatus to create ring- and torus-shaped traps. These traps will be used to investigate the transition of a Bose-Einstein condensate when the dimensionality of the trapping geometry changes from 3D to 2D, and from 2D to 1D. Of particular interest are studies of low dimensional systems (2D and 1D) with periodic boundary conditions. Further we intend to use this configuration to create a Sagnac-like interferometer with ultracold atoms. The current progress of the experimental setup will be presented.
