Wigner representation of Bose-Einstein condensates in the Thomas-Fermi limit — •Jan Teske and Reinhold Walser — Technische Universität Darmstadt

In 2017, the MAIUS sounding rocket created the first Bose-Einstein condensate in space and realised a matter-wave interferometer [1]. In general, atom interferometers serve as high precision sensors for accelerations, gravity and gravity gradients with a wide range of scientific and technological applications.

Simulating cold quantum gases is mostly done with classical mean fields or with ray tracing simulations in phase space. It is therefore necessary to have simple approximation schemes for interacting BECs in the Thomas-Fermi limit in phase space. In the present contribution, we compare analytical approximation for the Thomas-Fermi Wigner functions with a full Gross-Pitaevskii mean field simulation.
