RESEARCH
OVERVIEW
Materials around us display ample variety of physical properties. As has been the way for thousands of years, scientists try to understand the origin (microscopic mechnaism) of such properties. The electronic structures or the behaviour of the electrons in solids quite often determine the physical properties (figure).

The general goal of our reserach is to measure the electronic structures and understand the microscopic mechanisms of various novel physical properties. The materials we are interested in are generally termed as correlated electron systems in which the electron-electron correlation results in exotic phenomena such as high temperature superconductivity and metal insulator transitions. We are especially interested in the phenomena originating from orbital degree of freedom, such as orbital order, orbital-angular-momentum-driven Rashba and spin Hall effect.

The main experimental technique used in our research is angle resolved photoemission spectroscopy or ARPES in short. ARPES can directly measure the band structure among other properties of matter, some of examples shown as in the figure. We currently have an ARPES system and planning to have an ultra-high resolution system this year. With new systems, we plan to do ultra-high resolution experiments as well as time resolved experiments in the near future.
