【Abstract】 Some investigations have been made about the evolution of the linear entropies for coherent excitonic states in the system of two coupled large semiconduction quantum dots mediated by a single-mode cavity field.The linear entropy attains the ideal case of being a periodic function of gt,it shows maximally entangled coherent exciton states can be generated in the case.The effects of the zero-temperature environment on the linear entropy of excitonic coherent state are also studied.更多还原
