Welcome just descirbe what is density of state and its physical meaning if you are tired of answering my more numerical question below!
My confusion mainly stems from this dilemaaa:
In momentum phase space:
weight(degeneracy) is:
[tex]g=\frac{V}{B}dp_{x}dp_{y}dp_{z}[/tex]
but suddenly the dp term vanishes in polar coordinates and becomes:
[tex]g=\frac{V}{B}4\pi p^2[/tex]
??
why the former has dp terms? Is degenracy equal to density of states in momentum space? Or is it a typo in my notes?
