Journal ArticleDOI
Green's function approach to the quantum many-body theory of the solid state
TL;DR: The Green's function approach is used to develop a quantum many-body theory of the solid state which should work at low temperatures as well as in the neighbourhood of phase transition points as discussed by the authors.
Journal ArticleDOI
On the spin-phonon interaction in anharmonic crystals
TL;DR: In this paper, a theory for examining the influence of spin-phonon interaction on the phonon dynamics in anharmonic crystals is developed for analyzing the role of the direct interaction between lattice vibrations with that of the indirect interaction via spins in the propagation and attenuation of sound as well as in the behaviour of thermodynamic quantities.
Journal ArticleDOI
Self-consistent renormalized phonons in metallic and nonmetallic solids
TL;DR: In this paper, an integral equation for the generalized Gruneisen function entering into the expression for the phonon self-energy is derived via the dielectric screening treatment of vibrational excitations.
