Abstract


Matter-wave interferometry provides an excellent tool to investigate the effect of the environment on coherence. I will present several interferometry experiments done with a BEC on an atom chip and in which different effects of the environment have been investigated. First, I will discuss effects of fluctuations in the nearby environment probed with atoms trapped in a lattice very close to the surface. Then I will present the effect of gravity probed by clock interferometry, which connects to the interplay of QM and GR and “clock complementarity”. Finally, I will discuss Stern-Gerlach interferometry and describe it in the context of time irreversibility.
