Motivated by a recent experiment [E. Nicklas et al Phys. Rev. Lett. (2015)], I consider the paradigmatic case of pre-thermal critical states of an interacting O(N) model, for studying universal real-time crossovers among the dynamical critical points of a macroscopic quantum system after a quench. These novel features of pre-thermal critical dynamics are extracted using a combination of renormalization group analysis and exactly solvable large N limit.
