Analysis of photon-atom entanglement generated by Faraday rotation in a cavity
- Department of Physics and Institute of Theoretical Physics, Chinese University of Hong Kong, Shatin, Hong Kong (China)
Faraday rotation based on ac Stark shifts is a mechanism that can entangle the polarization states of photons and atoms. We study the entanglement dynamics inside an optical cavity, and characterize the photon-atom entanglement by using the Schmidt decomposition method. The time dependence of entanglement entropy and the effective Schmidt number are examined. We show that the entanglement can be enhanced by the cavity, and the entanglement entropy can be controlled by the initial fluctuations of atoms and photons.
