Simulations of Integrated Laser-Guided Atom Interferometers — •Matthew Glaysher, Hannah Paltzer, Ernst Maria Rasel, and Naceur Gaaloul — Leibniz Universität Hannover, Institute of Quantum Optics, Germany

Atom interferometry provides a highly accurate measurement tool, its applications ranging from inertial sensing and navigation to tests of fundamental physics. High precision interferometry is achieved either by Large Momentum Transfer or long interrogation times. Whereas the more common light pulse interferometer schemes can produce the necessary momentum transfer, guided interferometers can achieve long interrogation times. For guided ensembles it is essential to understand the internal interactions, as well as the continuous interactions with a light field, to realize a phase-sensitive interferometer. For this purpose we combine the computation of the dynamics of Bose-Einstein Condensates (BECs) by numerically solving the Gross-Pitaevskii-Equation (GPE) and classical n-particle simulation. We specifically investigate beam-splitting mechanisms and the phase evolution of BECs in a guided system, in which the guide is realized by dynamically shaped cavity modes or painted potentials.
