| Abstract: | The time evolution of distance between density operators in degenerate Raman two- photon coupling system inside a phase-damping are investigated . The influences of phase damping and the mean photon munber of the field on the distance between density opertors are discussed . The results show that the existence of cavity phase damping leads to the phenomenon that the quan- tum states of the field and the system deviate from the initial pure state. |
