Box potentials for 2D atomic clouds

Laboratoire Kastler Brossel, ENS and Collège de France, Paris

Progress in tailoring optical potentials has enabled to study how Bose-Einstein condensates behave in different geometries. We have developed a technique to imprint uniform potentials on a flat atomic gas, which eases the study of critical phenomena. In this talk, I will present the result we obtained on condensation of atoms in 2D box potential, showing that phase coherence in our system appears due to transverse condensation rather than other mechanisms. We also study this transition by quench cooling the atoms and looking at topological defects. Then, I will present the new experimental setup under construction aimed at producing rings of atoms to study condensation in presence of an artificial magnetic field.
