HDR defense of Rémi Geiger the 28th of June, 2019 at Observatoire de Paris

Rémi GEIGER will defend his “habilitation à diriger des recherches” on 28th June 2019 at 2:00 pm on the subject “Atom interferometry: from fundamental physics to precision inertial measurements”.

The defense will take place at Observatoire de Paris (77 av. Denfert-Rochereau, Paris 14ème) in Salle Cassini, Bâtiment Perrault.

Abstract:

Interferometry with matter waves dates back to the first ages of quantum mechanics as the concept of matter waves played a key role in the development of the quantum theory. Performing interference experiments with various types of matter-waves has driven the efforts of several communities working with electrons, neutrons, atoms, molecules, or anti-matter. The field of atom interferometry has developed rapidly within the atomic physics community and even more since the advent of laser cooling techniques in the 1980s, which offers a high level of control. Cold-atom interferometers are nowadays studied by more than 40 research laboratories in the world and developed in several companies. They address a large panel of applications in tests of fundamental physics, metrology, geosciences, inertial navigation or gravitational wave astronomy. In this presentation, I will describe some of my research projects related to the measurements of gravitational and inertial effects with cold-atom interferometers within the atom interferometry and inertial sensor team of SYRTE at Paris Observatory.
