Abstract
Photoinduced 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.
