  Real time rearrangement of particle spectra is studied numerically in a U(1)
Gauge+Higgs system, in the unitary gauge and in three spatial dimensions. The
cold system starts from the symmetric phase. Evolution of the partial energy
densities and pressures reveal well-defined equations of state for the
longitudinal and transversal gauge fields very early. Longitudinal modes are
excited more efficiently and thermalize the slowest. Hausdorff-dimension of the
Higgs-defect manifold, eventually seeding vortex excitations is thoroughly
discussed. Scaling dependence of the vortex density on the characteristic time
of the symmetry breaking transition is established.
