Absorption imaging of a quasi 2D gas: a multiple scattering analysis
L. Chomaz, L. Corman, T. Yefsah +2
Absorption imaging with quasi-resonant laser light is a commonly used technique to probe ultra-cold atomic gases in various geometries. Here we investigate some non-trivial aspects…
Dynamic Kosterlitz-Thouless transition in 2D Bose mixtures of ultra-cold atoms
L. Mathey, Kenneth J. Günter, Jean Dalibard +1
We propose a realistic experiment to demonstrate a dynamic Kosterlitz-Thouless transition in ultra-cold atomic gases in two dimensions. With a numerical implementation of the Trunc…
Optical Flux Lattices for Two-Photon Dressed States
Nigel R. Cooper, Jean Dalibard
We describe a simple scheme by which "optical flux lattices" can be implemented in ultracold atomic gases using two-photon dressed states. This scheme can be applied, for example,…
Exploring the thermodynamics of a two-dimensional Bose gas
Tarik Yefsah, Rémi Desbuquois, Lauriane Chomaz +2
Using \emph{in situ} measurements on a quasi two-dimensional, harmonically trapped Rb gas, we infer various equations of state for the equivalent homogeneous fluid. From the…
Can a Bose gas be saturated?
Naaman Tammuz, Robert P. Smith, Robert L. D. Campbell +4
Bose-Einstein condensation is unique among phase transitions between different states of matter in the sense that it occurs even in the absence of interactions between particles. I…
