SELF-CONSISTENT DESCRIPTION OF INTERACTING PHONONS IN A CRYSTAL LATTICE
Self-consistent approach for interacting phonons description in lattice, which generalizes Debye model, is proposed. Notion of “selfconsistent” phonons is introduced, speed of which depends on temperature and is determined from non-linear equation. Debye energy is also a function of temperature in t...
