| Research Abstract |
In order to achieve the control of electronic phase in molecular solids by lights, we newly developed high time-resolution pump-probe systems and time-resolved terahertz spectroscopy systems. Using them we have detected time evolutions of photoinduced neutral to ionic transition, insulator to metal transition, and melting of spin-density-wave state, and clarified physical mechanisms of those transitions. We have also succeeded in detecting ferroelectric polarizations in organic ferroelectrics and in controlling polarizations by terahertz fields. In addition, we have successfully detected band structures and Fermi surfaces in molecular conductors by using angle-resolved photoelectron spectroscopy.
