Tackling leading order uncertainties in atom gravimetry — •Nina Grove, Maral Sahelgozin, Jonas Matthias, Jan Philipp Barbey, Sven Abend, Waldemar Herr, and Ernst M. Rasel — Inst. f. Quantenoptik, Leibniz Universität Hannover
On our poster we will discuss the limiting systematic effects in state-of-the-art atom gravimeters and present our estimations for mitigating these uncertainties in our novel transportable Quantum Gravimeter QG-1. The improved performance will be made possible by employing magnetically lensed Bose-Einstein Condensates as the source for the atom interferometer, as the current generation of atom gravimeters are limited by the use of thermal laser cooled atomic ensembles. By this the leading systematic error caused by wavefront aberrations and the Coriolis force will be suppressed. Approaching an accuracy of 10−9m/s2 novel contributions to the uncertainty budget, namely shifts due to mean field energy and the Black Body Radiation, will be discussed.
