A. Research Areas~
#br
Our research interest is to explore optical properties of various condensed matters with various spectroscopes. By revealing the interaction between light and matters, we give rise to new functional phenomena related to underlying peculiar phases induced by photo-excitation.
#br
The current research topics can be divided into the following:

    * Photo-induced phase transition
    * Ultrasfast spectroscopy
    * New spectroscopy in THz frequency region
    * New laser spectroscopy to reveal phase transition in ferroelectric or ferromagnetic materials
    * Pulse magnetic resonance spectroscopy in functional light-emitting materials
