Resumen:
We present a study of the freezing dynamics of topological defects in a subcritical system by
testing the Kibble¿Zurek (KZ) mechanism while crossing a tri-stable region in a
one-dimensional quintic complex Ginzburg¿Landau equation. The critical exponents of the
KZ mechanism and the horizon (KZ-scaling regime) are predicted from the quasistatic study,
and are in full accordance with the quenched study. The correlation length, in the KZ freezing
regime, is corroborated from the number of topological defects and from the spatial
correlation function of the order parameter. Furthermore, we characterize the dynamics to
differentiate three out-of-equilibrium regimes: the adiabatic, the impulse and the free
relaxation. We show that the impulse regime shares a common temporal domain with a fast
exponential increase of the order parameter.
