Experimental test of the universality of the Anderson transition with cold at...
In solid state physics, the study of the effects of disorder led to the discovery of a phase transition. For weak disorder, the solid is a conductor, whereas for... -
Macroscopic quantum coherent phenomena in Bose Josephson junctions
In recent years, cold atomic systems have been recognized as very promising tools for quantum simulators and for applications in quantum technology. In particular, a... -
Collective effects and interacting particles: From long-range systems to cold...
A large number of physical systems present long range interactions : self-gravitating systems, plasmas, vortex interactions... and thus share some properties. In this... -
Cooperative effects in cold atom clouds
In this thesis, we investigate experimentally as well as theoretically collective effects in dilute clouds of cold atoms. In order to study the competition between... -
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... -
