摘要
The dynamics of two identical two-level atoms in non-ideal cavity it is considered. Using approach developed before by us for case of one two-level atom, the analytical expression for density matrix of the system is presented. Dynamics of level populations, mean number of photons and correlation function for photons are calculated. Using Peres - Horodecki criteria exact expression for entanglement dynamics of two identical two-level atoms in cavity is given. Influence of detuning and damping constants are investigated.
