Développement d'une source de condensats de Bose-Einstein pour l'interférométrie atomique

Abstract : My thesis consists in developing a new atom interferometer using Bose Einstein condensate sources. This new interferometer aims to overcome current state of the art sensitivity, and will be used to perform equivalence principle test, quantum electrodynamics, and theories beyond standard model. During my PhD, I designed and built a new interferometer to perform a test of atom electrical neutrality by taking advantage of the scalar Aharanov-Bohm effect. In this manuscript, I present, in a first part, the ultra-cold atom source obtained with an all optical method. An evaporation cooling was performed on a cloud of 3.109 atoms with a temperature of 20 µK to end up with a pure condensate of 2.104 atoms. In a second time, a laser setup was designed and built to create an optical diffraction lattice. In the meantime, a part of my work also consisted in developing a mesoscopic atom chip. The use of atom chip allows to considerably reduce the dimension of the apparatus, it requires a low electrical power and allows a high duty cycle. Such a technology offers new perspectives regarding space missions.
