Partition Function, Grand Potential

  1. Mar 8, 2014 #1
    It seems like they have missed out a factor of ##(2S+1)## in the final expression for grand potential? I'm thinking it should be ##(2S+1)^2## instead.

    I don't know, didn't they write the (2S+1) factor twice? There are 2S+1 states for each value of k, so in Eq.(30.3) you can put this factor in front of the integral, or include it in g(E), but you should not do both!
