Vibrational density of states and homogeneous linewidth in molecular crystals: Many-phonon processes in nitrogen

RG Della Valle, GF Signorini, P Procacci - Physical Review B, 1997 - APS
This paper summarizes, simplifies, and extends some recent developments in the theory of
phonon damping in anharmonic crystals. We propose an approach in which the damping is …
