The sudden death and revival of the atomic entanglement
Xiaoping Li · Jiguang zazhi · 2008
In this paper,the atomic entanglement evolution in the system of two atoms interacting with vacuum is investigated making use of Λ function and negative entanglement theory.The result shows that the sudden death and revival of the atomic entanglement,the good correspondence between Λ function and negative entanglement,the state being both mixed and separable expressed by Λ0 which can not be expressed by negative entanglement theory and C funciton,and the initial state's effect on entanglement property.
