Özet
The dynamics of atom-field entanglement for a system composed of two atoms resonantly coupled to a single mode leaky cavity field has been investigated beyond rotating wave approximation (RWA). By using a monogamic relation for the entanglement of formation (EOF) as well as the lower bound of the EOF for bipartite mixed states in higher dimensions, contrary to the RWA case, the atom-field system in the steady states is found to be entangled in the strong-coupling regime and the entanglement can grow as a function of atom-field coupling strength.
