I = have a bunch of literature on the topic, but none of this is what I'm = looking for. The literature I've found is all very formal and = algebraic; this is important I know but what I want is a really = pedantic, yet thorough exposition with examples to cut my teeth on - = just to make sure I really understand how to apply the technique to the = specific systems in front of me. Something at the level of an advanced = graduate text would be good, except that I can't seem to find any. I'm = specifically interested in canonical perturbation theory leading at all = orders to a Hermitian effective Hamiltonian (i.e. Van-Vleck, Des = Cloiseaux-type Hamiltonians). I would very much like it if it was = really, really, transparent and pedantic. Any suggestions?

Dear CCL,


I am interested in calculating / predicting the heat capacity and vibrational entropy for an anisotropic crystal.  I believe a density of states (density of phonon modes) calculation is the way to go.  Does anyone know of a good basic reference for the anisotropic Debye model?  Or is there another approach you think would be better?  I have found good descriptions of the isotropic Debye model, so I am looking for the extension to the anisotropic case.


Thank you in advance,
