Homework Statement
here's a problem I'm having a little bit of trouble with.
A)The high temperature limit of the einstein model gives Cv = 3Nk, Find the next order correction in the high temperature limit.
B)Show that the first correction to the specific heat in the debeye model in the low temperature limit is: 9Nk(theta/T)exp(-theta/T).
C)Find an expression for the heat capacity of a two-dimensional square crystal in the debeye approximation. show that Cv is proportional to T^2 in the low temperature limit.
I'm not sure how to start or approach this problem, any help with either of the parts would be greatly appreciated.
Homework Equations
The Attempt at a Solution
my first thought was to use the summation or intergral of the energy to find the next order and then use Cv = dE/dT, but I am not entirely sure how to set it up.
