Research Interests
  • Study on quantum effect in metal-hydride
    keyword : hydrogen, quantum effect
    2014.05.
  • New phenomena in f-electron systems at low temperatures
    keyword : Heavy Fermion, Valence Fluctuation, Non Fermi Liquid, Quadrupolar fluctuation, Point-contact spectroscopy
    2000.04Physics related to the fluctuation of quadrupolar moments are a fascinating new topic in strongly correlated electron systems which developed after the middle of 1990's. My current interest is the problem how the quadrupolar fluctuation is suppressed, if the qudrupolar ordering does not occur down to 0K..
  • Investigation of the electrical conductance in atomic-size wires and contacts.
    keyword : Conductance in atomic-size wires
    2007.04Quantum Conductance in Nanowires and Molecules.
  • Experimental study of novel properties in nanoscale superconductors
    keyword : Superconductivity, surface
    2014.04.
  • Development of experimental technique in multiextreme conditions: low temperature, high magnetic fields and high pressure.
    keyword : Multiextreme conditions: low temperature, high magnetic fields and high pressure
    2000.01Development of electric, magnetic and thermal measurements in extreme environments..
  • Investigation of anomalos properties in low dimensional and organic magnets
    keyword : Low dimensional spin system, Quantum spin system, Spin gap system, Frustration magnet
    2000.04The studies of low-dimensional magnetic systems such as Haldane compounds have played an important role in the development of the quantum statistical physics. I am investigating low temperature and high magnetic field properties of the low-dimensional systems with weak frustration of the magnetic interactions..
