We investigate the inhomogeneous chiral dynamics of the O(4) linear sigmamodel in 1+1 dimensions using the time dependent variational approach in thespace spanned by the squeezed states. We compare two cases, with and withoutthe Gaussian approximation for the Green's functions. We show that mode-modecorrelation plays a decisive role in the out-of-equilibrium quantum dynamics ofdomain formation and squeezing of states.Comment: 5 pages, 4 figures.
