Entanglement of atomic states upon collective radiative decay
Ashat M. Basharov · Journal of Experimental and Theoretical Physics Letters · 2002
It is shown in the Markovian approximation that the relaxation of two atoms noninteracting with each other in the field of a common thermostat results in the entanglement of atomic states. With time, this entanglement either vanishes or takes a stationary value depending on the initial conditions.
