A ring trap for ultracold atoms

Résumé

We propose a new kind of toroidal trap, designed for ultracold atoms. It relies on a combination of a magnetic trap for rf-dressed atoms, which creates a bubble-like trap, and a standing wave of light. We study the trap characteristics for a set of experimentally accessible parameters. The trap loading procedure is also addressed, as well as the question of dimensionality of a Bose-Einstein condensate in the ring potential.
