I'm studying by Statistical Mechanics (Huang, page 180) but can't understand many things there, can anyone provide a good bibliography to study this? I don't understand what's an occupation number of a given momentum: if it's the number of particles with that given momentum, why can it only be 0 or 1 in Fermi gas, doesn't the gas has a lot of particles which can possibly have that momentum? And why is momentum written like:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]p = \frac{h}{L}\underset{n}{\rightarrow}[/tex]

where n is a vector which components are 0 or integers, and L is the cube root volume of the system.
