文摘Entanglement dynamics of the atoms in the double Jaynes-Cummings models with the Kerr medium isstudied, and the effect of the Kerr medium on that is examined.The result shows that, the Kerr medium can control theentanglement dynamics of the atoms and repress entanglement sudden death.We can obtain the maximum entanglementbetween the atoms by strengthening the nonlinear interaction of the Kerr medium.
