I started my research carrier at Prof. Kenichi Fukui’s (Nobel Prize laureate of chemistry in 1981) laboratory in Kyoto University where I finished my thesis “A theoretical study of the vibronic coupling in molecules”. Just after finishing my thesis, I joined Dr. Jun Kondo’s condensed matter theory group in the Electrotechnical Laboratory. Thus, my academic interest covers wide range topics in condensed matter physics, computational physics and quantum chemistry from single molecules to bulk materials. It includes non-equilibrium transport, charge migration, strong correlation, many-body effect, superconductivity, chemical reaction, vibronic coupling, electron-phonon interaction, etc. My research achievements include theory of inelastic electric current, the self-consistent theory of electron and phonon currents, theory of the local heating, and theory of vibronic effects on current noise. Some publications in these topics are listed below:
