The characteristic properties of atom-field entanglement in various two-photon Tavis–Cummings models are considered both in terms of wave function dynamics and linear entropy dynamics for several initial pure atomic states and a strong coherent field. The expressions for disentanglement times are found for each model. The initial pure atomic states, which are necessary for the disentanglement of subsystem states, are determined.
Keywords: atom-field entanglement, linear entropy, wave function dynamics, two-photon Tavis–Cummings model, Raman interaction, nondegenerate two-photon interaction, degenerate two-photon model.
Mots-clés : disentanglement time
