One-dimensional description of a Bose-Einstein condensate in a rotating closed-loop waveguide

Abstract

We propose a general procedure for reducing the three-dimensional Schrödinger equation for atoms moving along a strongly confining atomic waveguide to an effective one-dimensional equation. This procedure is applied to the case of a rotating closed-loop waveguide. The possibility of including mean-field atomic interactions is presented. Finally, application of the general theory to characterize a new concept of atomic waveguide based on optical tweezers is discussed. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
