Numerical simulation on the dynamics of photoinduced cooperative phenomena in molecular crystals

Site-dependent lattice dynamics of photoinduced structural change

“…Details of the method of calculation are described in Ref. 16 and we do not mention it further to avoid redundancy. Here we only note that the nucleation process in the present model appears as the growth of "islands" of molecules in the excited electronic states ͉ ↑ ͘ r ជ , and that it is driven by the propagation of coherent phonons.…”
