| Abstract | ||
| In this paper, based on the Jaynes-Cummings model, the Hamiltonian of a system consisting of two nonidentical two-level atoms and a quantized electromagnetic field is introduced, in the presence of dipole-dipole interaction and Kerr-like medium. In order to arrive at the wave function of the system, the Schrödinger equation in the interaction picture is analytically obtained in a specific situation: one of the atoms in a resonance and the other in a non-resonance. Then, the atomic population inversion, entanglement between two atoms, and entanglement between two atoms and the field are numerically investigated. The results indicate that dipole-dipole interactions and detuning have a more significant effect on the quality of population inversion than the Kerr effect. Furthermore, for both atom-atom and atom-field entanglement, the data show that dipole-dipole interaction enhances entanglement more strongly than the Kerr effect. | ||
