In the context of the AdS/QCD correspondence, it was proposed that the
melting process of mesons in quark-gluon plasma can be modeled by
perturbative motion of a probe brane in the asymptotically AdS black
hole background. Within this setup, we study dynamical phenomena induced
by thermal quench using numerical technique to solve nonlinear dynamics
of the probe brane. As a result, we find a new nonequilibrium state in
which the mesons melt temporarily even though the final temperature is
lower than the meson melting temperature. After explaining the bulk
gravity process corresponding to this state, we argue implications of
this result to the boundary QCD.
