Atom interferometry with ultracold thermal clouds and realistic laser pulses — •Jens Jenewein, Albert Roura, Wolfgang P. Schleich, and the QUANTUS Team — Universität Ulm, Ulm, Germany

We have developed a real-time simulation for a symmetric and an asymmetric Mach-Zehnder like light-pulse atom interferometer. Realistic laser pulses of arbitrary shape are employed based on single and double Bragg diffraction leading to velocity selectivity and excitation of off-resonant diffraction orders. This feature makes the simulation which also includes lensed thermal atoms more feasible for the description of experiments. We can also estimate the contrast C that contributes together with the atom number to the sensivity. Various effects such as delta-kick collimation and the amount of evaporative cooling affect C.
