About Us | Junichiro Kono Laboratory

Research:

Our research is focused on light-matter interactions. We use light to drive or probe quantum states in condensed matter — nanomaterials, magnets, strongly correlated materials, and superconductors — under extreme conditions of temperature and magnetic fields. Our research will lead to a microscopic understanding of nonequilibrium cooperative phenomena of many-electron systems as well as to novel device concepts and implementations, especially towards the solid-state realization of quantum information processing, computation and communications. Our lab is equipped with state-of-the-art spectroscopic instruments and techniques to study charge, spin, and vibrational dynamics in a variety of modern materials, either in free space or in cavities.
