Abstract:The effects of the initial field state and thermal environment on quantum nonlocality in atom-field coupling system are investigated. It is found that if the cavity dissipation is very weak and the average photon number of thermal environment is very small, the atom-field state can exhibit quantum nonlocality periodically. The rapidity of the loss of the quantum nonlocality depends on the amplitude of the initial squeezed vacuum state and the cavity damping constant and the average photon number of thermal environment. The stronger the field is and the larger the damping constant and the average photon number could be, the more rapidly the nonlocality decreases.
