Towards a guided atom interferometer based on a superconducting atom chip — Tobias Mueller, Xing Wu, •Anushyam Mohan, Azar Eyvazov, Yu Wu, and Rainer Dumke — Division of Physics & Applied Physics, School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore

We evaluate the realization of a novel geometry of a guided atom interferometer based on a high temperature superconducting micro-structure [1]. The interferometer type structure is obtained with a guiding potential realized by two current carrying superconducting wires in combination with a closed superconducting loop sustaining a persistent current. We present the layout and realization of our superconducting atom chip. By employing simulations we discuss the critical parameters of the interferometer guide in particular near the splitting regions of the matter waves. In the talk, we present the actual status of the experiment.
