Interferometry Team

The atom interferometer team of LCAR (Toulouse-France) is interested in interferometry with Matter-wave.
In particular, we have been developing atom interferometers with separated arms. These interferometers allow to set up controled perturbations on a single path.

The high sensitivity of quantum interference patterns to these external perturbations can be exploited to measure weak external forces or internal atomic properties with high sensitivity. In particular, our experiments are designed to test the electromagnetic interactions, such as Atom polarisability, Atom-atom interactions, Atom-surface interaction, Atom neutrality. These measurements might have applications in fundamental physics and atom metrology. We also study curiosity of quantum mechanics : Topological phase shift, decoherence and dephasing.
