Abstract
AbstractPhotoinduced transition dynamics is studied in extended Peierls‐Hubbard models for organic BEDT‐TTF salts on anisotropic triangular lattices. For θ‐ and α‐type salts, the lattice distortion pattern in the charge‐ordered ground state governs the easiness of the insulator‐to‐metal transition. For κ‐type salts, the energy of photoexcitation in the dimer‐Mott phase determines whether the insulator‐to‐metal transition is controlled by the bandwidth or the band filling.
