The peculiarities of atom-field entanglement in the model of two nonidentical atoms interacting with one-mode coherent electromagnetic field in lossless cavity via degenerate two-photon Raman transitions have been investigated. The times of atoms and field states disentanglement have been calculated on the basis of time-dependent wave function behavior and the linear atomic entropy concept.
Keywords: atom-field entanglement, two nonidentical atoms, degenerate two-photon Raman transitions, linear atomic entropy.
