comment How are the PPT criterion and Bell's inequality different?
As soon as you write a density matrix $\rho$ or quantum mechanical operators $A\otimes B$, you are in the framework of quantum mechanics. The generality of hidden variables is lost as soon as you enter the description of quantum mechanics. Therefore the expression $\rho(\lambda)$ makes not much sense in this context.

comment Expansion in solid spherical harmonics on the lattice
Do you think of some expansion as in real space Wannier functions? But unfortunately these functions can not be used explicitely as I remember... In addition you will need the interaction Hamiltonian to describe the scattering in the correct shape. Please be more specific what is scattered on the lattice sites!?

comment Historic derivation of Wien's law
@EmilioPisanty: What would be $f$ in your understanding? One has to assume of course also a force free and isotropic system for Maxwell-Boltzmann distribution too. It is derived from Boltzmann transport equation as you might know or see itp.phys.ethz.ch/education/lectures_hs12/StatPhys/… at chapter 2.4.

comment Finding the Electric Field (and other information, besides)
@EliMackenzie: Ok, I might have overestimated your skills. You maybe also want to have a look at Purcell's electricity and magnetism but there is no short explanation either. You have to collect the formulas from different sections there.
