RESEARCH

The main topic of my research has been the electronic properties of strongly correlated materials such as cuprates and Iron-based high-Tc superconductors studied through the observation of band structure by angle-resolved photoemission spectroscopy (ARPES). Currently I focus on the subject on the novel topological states occurring with the strong spin-orbital interaction as well as the strong electron correlation.
The aim for this research project is to develop the physics on the novel topological phases realized in strongly correlated electron systems by using the state-of-the-art photoemission spectroscopy with angle-, spin-, and time-resolved capabilities.
