Yong Baek Kim studies theory of intriguing quantum phases of matter in strongly interacting condensed matter systems. He investigates the properties of novel elementary excitations in such quantum states of matter, which may be ingenuously used in experiments to design and control the electronic and magnetic properties of these systems. His recent research works concentrate on theory of frustrated magnets, quantum spin liquid, superconductivity, and topological insulators.
