Description
We study the dynamics of chiral phase transition in the O(4) linear sigma model by using the time-dependent variational approach with squeezed states. Our numerical simulations show that large domains of the disoriented chiral condensate (DCC) are formed through the mode-mode correlation. We also present a result of an analysis of the two-particle correlation function for the pion fields, which reflects unique nature of the squeezed states. In particular, we will show that the chaoticity parameter is not close to zero even if DCC domains are produced
