Shortcuts to adiabaticity for ultracold gases
In this thesis I explore the possibility of accelerating adiabatic processes for quantum systems. Experiments are performed with a trapped ultracold gas of Rubidium-87... -
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... -
Shape oscillation of a rotating Bose-Einstein condensate
We present a theoretical and experimental analysis of thetransverse monopole mode of a fast rotating Bose-Einsteincondensate. The condensate's rotation frequency is... -

Matter wave scattering on complex potentials
The first part of this thesis concerns the development of a novel type of Zeeman slower (ZS) that is based on permanent magnets and has several advantages over the... -
Bose-Einstein condensate in a dressed trap: collective modes in a two-dimensi...
This thesis presents the production of a degenerate rubidium 87 gas in the quasi two-dimensional (2D) regime and the study of collective modes of this gas. We show... -
Dynamics of ultracold quantum gases in correlated disordered potentials
The topic of this thesis is the study of localization of a quasi-one-dimensional and harmonically trapped Bose-Einstein condensate through which various disordered... -
Second-order coherence of superradiance from a Bose-Einstein condensate
We have measured the 2-particle correlation function of atoms from a Bose--Einstein condensate participating in a superradiance process, which directly reflects the...
