Collective dynamics of two two-level and three-level atoms with nondegenerate two-photon transitions in two-mode cavity

Abstract

The entanglement between two identical two-level atoms interacting with two mode thermal field through a nondegenerate two-photon process has been suggested. The role of detuning has been illustrated by the example of simple one-mode two-atom model.

Entanglement for atoms with degenerate two-photon transitions successively passing the thermal cavity

Eugene K. Bashkirov, Yulia A. Nikiforova

The entanglement between two identical two-level atoms successively passing thermal cavity and interacting with one-mode thermal field through a degenerate two-photon process is investigated. It is shown that two atoms can be entangled through such nonlinear interaction.

Entanglement induced by the two-mode thermal noise

Eugene K. Bashkirov

The entanglement between two identical two-level atoms interacting with a two-mode thermal field through a nondegenerate two-photon process is investigated. It is shown that two atoms can be entangled through a nonlinear nondegenerate two-photon interaction with two-mode thermal field. On the contrary, for the two-atom Raman coupled model the entanglement is impossible.

Atom-atom entanglement in a not-resonant two-photon Tavis-Cummings model

Maria O. Guslyannikova, Eugene K. Bashkirov

The entanglement between two two-level atoms (qubits) interacting not-resonantly with a one mode of thermal field in a lossless cavity via effective degenerate two-photon transitions is investigated. Based on the exact solution for the time-dependent density matrix of the system under consideration, negativity is calculated as a measure of the entanglement of atoms. The influence of a detuning on the dynamics of entanglement of atoms for separable and entangled initial atomic states and thermal cavity state is investigated.

Dynamics of the two-atom Jaynes-Cummings model with nondegenerate two-photon transitions

Eugene K. Bashkirov

An exact solution is found for the collective model of two identical two-level atoms that resonantly interact with a two-mode quantum electromagnetic field in an ideal cavity via two-photon nondegenerate transitions. In the case under study, at the initial moment, both field modes are in the coherent state and atoms are in the excited state. The time dependences of the atomic probabilities, the mean number of photons in the modes, and the statistics and squeezing of the photon modes are studied based on the exact solution.

Entanglement induced by two-mode thermal noise taking into account the dipole-dipole interaction and atomic coherence

Eugene K. Bashkirov, Ekaterina Gennadievna Mangulova

The entanglement of two two-level atoms with the nondegenerate two-photon transitions interacting with two-mode thermal field in lossless cavity has been considered. The possibility of entanglement degree growth in the presence of an atomic coherence and direct dipole-dipole interaction of atoms has been derived.
