Bose Einstein Condensation

  1. Nov 18, 2013 #1
    my course just provided an introduction to Bose-Einstein Condensation.

    I was told that this phenomenon occurs when the temperature of Bosons go under a certain critical temperature [itex]T_{c}[/itex] > 0K. At absolute zero, all the Bosons go into the condensed phase.

    However, at temperatures between 0K and [itex]T_{c}[/itex], there is a mixture of an ideal Boson gas and condensed bosons.

    What then is the fugacity of the boson gas in such an instance?

    The chemical potential is exactly 0, which corresponds to fugacity 1, I suppose. Hence the density of non-condensed bosons becomes a function of T, only for T<Tc.
