Scientific paper

An attempt is made to clarify realization of a classical distribution from quantum fluctuations of the order parameter in the inflationary universe. We discuss destruction of quantum coherence associated with a state of the order parameter in models where it interacts with the environment. For that purpose, the time evolution of the reduced density matrix rho tilde, which is obtained by coarse-graining of the environment, is investigated. It is shown that off-diagonal elements of rho tilde decrease as the phase transition proceeds.
