Study on transfer induced BEC dynamics in optical waveguides — Sebastian Bode, •Felix Kösel, and Knut Stolzenberg — Institut für Quantenoptik, Hannover, Deutschland

Presentation of the experimental steps towards optically guided atom-interferometry using ⁸⁷Rb Bose-Einstein condensates. By applying a waveguide the evolution time of the ensemble is increased leading to higher sensitivity of the atom interferometer [1]. Beam-splitters and mirrors will be implemented via Bragg-pulses coupling to the momentum states of the atoms. Furthermore the transfer behaviour of the BEC from a crossed optical dipole trap into the optical waveguide is studied. The aforementioned behaviour results in complex dynamics which become apparent through fragmentations of the BEC due to phase fluctuations.
