  We study the kinetics of chiral transitions in quark matter using a
microscopic framework (Nambu-Jona-Lasinio model) and a phenomenological model
(Ginzburg-Landau free energy). We focus on the coarsening dynamics subsequent
to a quench from the massless quark phase to the massive quark phase. The
morphology of the ordering system is characterized by the scaling of the
order-parameter correlation function. The domain growth process obeys the
Allen-Cahn growth law, $L(t)\sim t^{1/2}$. We also study the growth of bubbles
of the stable massive phase from the metastable massless phase.
