Localization of a macroscopic object induced by the factorization of internal adiabatic motion

To account for the phenomenon of quantum decoherence of a macroscopic objec t, such as the localization and disappearance of interference. we invoke th e adiabatic quantum entanglement between its collective states (such as tha t of the center-of-mass (CM)) and its inner states based oil our recent inv estigation. Under the adiabatic limit where motion of the CM does not excit e the transition of inner states, it is shown that the wave function of the macroscopic object can be written as an entangled state with correlation b etween adiabatic inner states and quasi-classical motion configurations of the CM. Since the adiabatic inner states are factorized with respect to eac h component of the macroscopic object, this adiabatic separation can induce the quantum decoherence. This observation thus provides us with a possible solution to the Schrodinger cat paradox.
