The photoinduced domino effect for the phase transition dynamics in one‐dimensional electron–lattice systems is investigated to clarify the dependence on the friction (energy dissipation rate) and the interaction between neighboring sites. We find a novel photoinduced domino process in the case of strong intersite interaction and weak friction. In this domino motion the photoexcited site remains in an excited electronic state, which is in striking contrast to the conventional domino effect. We identify a region where the domino processes take place as a function of the intersite interaction and the friction. It is shown that the novel process remains, even in the case of a higher potential barrier between two phases.
