Ultracold atoms confined in rf-induced two-dimensional trapping potentials

We present the experimental implementation of a new trap for cold atoms proposed by O. Zobay and B. M. Garraway (Phys. Rev. Lett. 86 (2001) 1195). It relies on adiabatic potentials for atoms dressed by a rf field in an inhomogeneous magnetic field. This trap is well suited to confine atoms tightly along one direction to produce a two-dimensional atomic gas. We transferred ultracold atoms into this trap, starting either from thermal samples or Bose-Einstein condensates. In the latter case, technical noise during the loading stage caused heating and prevented us from observing 2D BECs.
