Nondestructive detection for atom interferometry and Bose-Einstein condensati...
In this thesis, we study several methods to improve atom interferometers. In the first part of the manuscript, we analyze how a nondestructive detection, that... -
Conception and realisation of a cold atom gravimeter
We present the realisation of a matter wave interferometer which measures the acceleration<br />of gravity. The wave-packets of 87Rb atoms are manipulated with... -
Étude d'états atomiques à proximité d'une surface massive - Application à l'e...
This thesis presents the theoretical modeling of the experiment FORCA-G (FORce de CAsimir et Gravitation à courte distance) currently in progress at Paris Observatory.... -
Atomic interferometers in an optical lattice
The aim of the ForCa-G project, for Casimir force and short range Gravitation, lies into the measurement of short range forces between atoms and a mirror using atomic... -
Experiments in atom interferometry : measurement of the He-McKellar-Wilkens a...
The family of topological phases of electromagnetic origin consists of the Aharonov-Bohm (AB) phase predicted in 1959 and of the Aharonov-Casher (AC) and... -
Raman interferometry with free-falling and trapped atoms
Since about twenty years atom interferometers have been studied for measuring inertial forces to high precision with atoms in free fall. The use of cold atoms was key...
