These two many-body problems are then treated differently: the electron problem in the Hartree-Fock approximation leading to single electron states and specifically to band structure for crystals; the atomic dynamics of crystals as collective excitations which when quantized lead to ph

U. Kreimeier,Zh. Yang,K. Messmerariton dispersion relation and damping. Measurements of bulk polaritons by light scattering and nonlinear optical processes are reviewed. The linear response theory is extended to a dielectric medium with a flat surface, thus providing the surface polariton dispersion relation and damping. Measureme
