摘要
The time evolution of the linear entropy of an atom in k-photon Jaynes-Cummings model is investigatedtaking into consideration Stark shift and Kerr-like medium. The effect of both the Stark shift and Kerr-like medium onthe linear entropy is analyzed using a numerical technique for the field initially in coherent state and in even coherentstate. The results show that the presence of the Kerr-like medium and Stark shift has an important effect on theproperties of the entropy and entanglement. It is also shown that the setting of the initial state plays a significant rolein the evolution of the linear entropy and entanglement.
