RELAXATION OF LOCAL PERTURBATION IN A QUANTUM VIBRATIONAL SYSTEM,

Abstract

Relaxation of local perturbation in a quantum vibrational system in harmonic approximation is examined. The relaxation of oscillatory energy in an electron-vibrational transition in the impurity center of a crystal is an example of processes of such type. General formulae describing the relaxation of state and energy, localized in the region of perturbation are obtained. In the case of a monatomic chain with isotopic defect calculations of laws of relaxation are reduced to numerical values and presented in the form of graphs. Laws of disintegration have a complex oscillatory form. The result of calculation of relaxation of mean oscillatory energy of impurity atom for the examined model will agree with results of the work of Zavt, where an analogous problem is solved by the methods of classical mechanics.
