With experimental realization of atomic Bose–Einstein condensation (BEC) and rapid
development of laser cooling and trapping techniques, all optical routes to quantum …

Zirconia, pure and modified by sulfate or molybdate was prepared in a molten nitrate
medium. Sintering, crystallization and the tetragonal–monoclinic (T–M) phase transition …

This thesis reports on photoassociation spectroscopy experiments on ultracold cesium
molecules, achieved through a series of benchmark measurements conducted with the …

A new scheme for trapping Cs atoms in a non dissipative trap has been developed. The trap
involves both optical dipole forces and magnetic forces. This device is suitable for Cs atoms …

Ce travail de thèse s' inscrit dans un effort de recherche entrepris depuis 1996 pour
atteindre la condensation de Bose-Einstein (CBE) de l'atome de césium. Les expériences …

In this Thesis we study the theory of fluctuations in quantum optical systems: from Bose-
Einstein condensates to squeezed states of light. The Thesis is divided into three parts …
