Population inversion evolution of entangled atoms in multiphoton anti-Jaynes-Cummings model

Abstract

Abstract:

When single mode coherent light field interacts with two identical entangled two-level atoms, the population number evolution of entangled atoms is studied by means of the multi-photon anti-Jaynes-Cummings model. The influence of average photon number of the coherent light field and transition photon number on the population number evolution of entangled atoms has been discussed. The result indicate that the probability difference which the excited state and the ground state of the entangled two-level atoms will decrease and whole of oscillation curves of the population number will rise with the increasing of the average photon number of the coherent light field；with the increasing of the transition photon number the probability difference which the excited state and the ground state of the entangled two-level atoms will increase and whole of the oscillation curves of the population number will descend.

Key words: quantum optics, multi-photon, population of entangled atoms, anti-Jaynes-Cummings model
