Yong Baek Kim Condensed matter theorist

Yong Baek Kim’s area of research is the theoretical study of quantum materials with strong electron interactions. His recent research activities focus on novel quantum phenomena in interacting electron systems with strong spin-orbit coupling. These include the emergence of topological phases where intriguing surface/boundary properties are characterized by topology of the bulk electronic states. He has also made important contributions to physics of quantum spin liquids where there exist the so-called spinons, “particles” carrying only the spin of the electrons, and an emergent “photon”. His research works are extended to a variety of subjects and materials including frustrated magnets, quantum magnetism, iridium oxides and other transition metal oxides with heavy elements, superconductors, and quantum phase transitions.
