Correlation between the atomic translational motion and its internal state population for the intensity-dependent coupling

Abstract
The influence of the atomic internal state population on its translational motion in a quantized standing-wave cavity field with spatial periodic structure is investigated for the intensity-dependent coupling case.On the basis of resonance interaction between the atom and the cavity field and with the aid of the atomic-field dressed state,the Schrodinger equations satisfied by the atomic translational motion for the two different atomic dressed internal states are built and their general relation for a spatial periodic cavity field is obtained.And under an appropriate approximation,the state vector of the whole system is derived and allows us to study the interaction between the atomic internal state and its translational dynamics.It is found that the scalar product of the translational motion wave functions in Hilbert space determines the atomic internal state population,as well as,the distortion of the atomic translational motion wave-packet is sensitivity to its initial internal state population for a quantized standing-wave cavity field at coherent state.
