Study on Linear Entopy of an Atom Contained in a Kerr Medium

Using super operator method,through the system master equation and the solution of matrix elements,we discuss two two-level atoms and Kerr medium containing cavity dispersion interaction system of atoms,light field,and the composite system of linear entropy evolution rule,the results show that the strong interaction of Kerr medium makes two atoms of system linear entropy and light field linear entropy produce complex concussion.
