Overview
Quantum Statistics for many particles. Consider a system consisting of N indistinguishable quantum particles. Grand partition function Z can be defined as..... (attached file shows equations). Answer the following:
(a) what is the grand partition function Z if the particles obey Fermi-Dirac statistics? and If they obey Bose-Einstein statistics.
(b) what is the average number of fermions (and bosons) n ?
(c) What is the dispersion Delta (n) of fermions? of Bosons?
