The research in the electronic structures group (ESG) is focused on electronic structure studies of strongly correlated systems, e.g. high-Tc superconductors, transition metal oxides and strong spin-orbit coupling materials. We are especially interested in the phenomena originating orbital degree of freedom, such as orbital order, orbital angular momentum driven Rashba and spin Hall effect.
While various novel and advanced spectroscopic techniques are used in the electronic structure studies in ESG, our main tool is the angle-resolved photoemission spectroscopy (ARPES). ARPES provides the most direct information on the electronic structures of materials such as band dispersions and Fermi surfaces. We currently have a home-lab based ARPES system with in-situ sample growth capability and are planning on constructing laser and discharge lamp based ultra-high resolution systems. We also use state of the art ARPES systems at synchrotron facilities around the world.
