Bose Einstein condensation in 2D finite space

  1. Nov 1, 2014 #1
    It can be easily proved that Bose Einstein condensation can be got in infinite 2D. But what about finite 2D with extreme large "Volume" L^2 ?

    Actually, you can't get BEC in an infinite 2D system. If the volume is finite, then you can get a coherence length greater than the size of the system, and have effective condensation. You can also constrain a 3D condensate so much along one direction that it behaves as an effective 2D condensate.

    Thank you very much. I should have typed cannot but somehow made a mistake.
