Entropy exchange and entanglement in Jaynes-Cummings model with Kerr-like medium and intensity-depend coupling

The effects of Kerr-like medium and intensity-depend coupling on entropy exchange and entanglement in Jaynes-Cummings model are investigated. Our results show that introducing the Kerr-like medium and intensity-depend is very helpful for improving the quality of entropy exchange. In addition, by the concept of the lower bound of the concurrence, the entanglement between the atom and the field under the influences of Kerr-like medium and intensity-depend coupling is also presented.
