On relaxation of entangled states in a collective thermostat
Ashat M. Basharov, В. Н. Горбачев · Optics and Spectroscopy · 2007
A kinetic equation describing collective relaxation process in the dispersion limit is derived for an ensemble of two-level atoms placed in a cavity and interacting with one cavity mode. Multiatom entangled states belonging to the set of Dicke states and insensitive to collective decay are found. A scheme for recording, storing, and reading these states with participation of spatially multimode light is reported.
