Quantum Transport of Matter Waves

Responsable : Vincent Josse

In close relation to the fundamental transport properties of electrons in condensed matter physics, we aim to study the quantum propagation of ultracold bosonic matter-waves through tailored optical potential. We focus on two main topics :

  • Anderson Localization of ultracold atoms in well controlled laser speckle disorder.
  • The guided atom laser : a new tool for studying quantum transport phenomena.

Direct observation of 1D Anderson Localization of an expanding Bose Einstein Condensate in a laser speckle potential [from Billy et al. Nature 493, 891 (2008)].

First evidence of 3D Anderson localization of an expanding Bose Einstein suspended against gravity and submitted to a 3D laser speckle potential [F. Jendrzejewski et al. to appear in Nature Physics (2012)]. This experiment paves the way towards the investigation of the celebrated Anderson transition between diffusive and localized states.

Realization of a guided atom laser by outcoupling a Bose Einstein Condensate directly into a optical waveguide (from W. Guerin et al., Phys. Rev. Lett. 97, 200402 (2006)).
