We mainly use angular resolved photoelectron spectroscopy (ARPES) to discover and understand phenomena that occur in quantum materials. Utilizing the advancement of modern ARPES technology, we will develop novel systems that can simultaneously perform spin detection, energy tunability, polarization control, and have micron spatial resolution and femtosecond time resolution. This ARPES, supplemented by material development and thin film growth, enables us to explore quantum phenomena with high selectivity and sensitivity, and to explore dynamic behavior on a natural time scale.

We also use other technologies in large facilities worldwide, such as micron spin rotation and relaxation (μSR), resonance inelastic X-ray scattering (RIXS), coherent diffraction imaging (CDI), X-ray magnetic circular dichroism ( XMCD) and other X-ray technologies to explore the electronic and magnetic structures in new types of quantum matter.
