Graduate Stirling's approximation in Fermi Statistics derivation
Also I have just realized that my previous statement "electron gas, the value of g_i=2" is plainly wrong as that is only the degenerate factor due to spin but not the whole degeneracy factor on 6D phase space. Thanks.- daktari

Graduate Stirling's approximation in Fermi Statistics derivation
Thanks. In fact I downloaded that article before posting on this forum, but the fact is that I don't find it very easy to follow. Thanks anyway!- daktari

Graduate Stirling's approximation in Fermi Statistics derivation
BTW, I was assuming "g_i" was the degeneracy of each energy state.- daktari

Yes, but those g_i values are not large numbers. Just think on an electron gas, the value of g_i=2, which is not large enough to support the use of Stirling's approximation.- daktari

Graduate Stirling's approximation in Fermi Statistics derivation
Hi People. I was looking at the derivation(s) of Fermi-Dirac Statistics by means of the "most probable distribution" (I know the correct way is to use ensembles, but my point is related to this derivation) and it usually employs Lagrange multipliers and Stirling's approximation on the...- daktari
