Non-Markovian Quantum Relaxation and Theory of Spectral Lines Width

Abstract: 

The quantum equation of relaxation with non-Markovian terms in the approximation of short-time memory is derived. The correlation functions for a single two-level atom and system of two dipole-dipole interaction of atoms in the external regular fields and the contour of the radiation lines are calculated. Accounting Non-Markovian effects leads to a more vivid expression of dipole-dipole interaction.

Key words: 
two-level atoms
non-Markovian kinetic equation
short time memory
radiation line contour
