Disordered two-dimensional gases

Team leader : Thomas Bourdel

  • Experiments with potassium and rubidium
  • Degenérate bose-fermi mixtures
  • Atom interferometry

We study two-dimensional (2D) quantum gases in the presence of disorder. Our experimental apparatus uses optical dipole potentials in order to evaporatively cool the atom cloud, to trap the atoms to 2D, and to add disorder using a speckle pattern. Our studies focus both on Anderson localization and on phase transitions in interacting quantum gases in the presence of disorder.

Picture of the experimental setup.

The atomic samples that we study are located in the middle of the science chamber in the center of the picture. Two large viewports with a diameter of 16 cm allow a good optical access to this area.

Scheme of the experimental setup

The atoms are trapped in the center of the science chamber. They are vertically strongly confined with an optical potential created from a phase plate 0-π. Disorder is created from a speckle pattern. The atoms are detected by fluorescent imaging on an amplified EMCCD camera.
