Dynamics of Photoinduced Phase Transition from a Dimer Mott Insulator to a Metal

We theoretically investigate the electron-phonon dynamics induced by photoexcitation in dimer Mott insulators of the form K-(BEDT-TTF)2X [BEDT-TTF: bis(ethylenedithio)-tetrathiafulvalene, X: a counteranion]. We adopt the quarter-filled extended Hubbard Hamiltonian coupled with the dimer-bond stretch...
