Dr. Ong is the Director of the Princeton Center for Complex Materials at Princeton University. He is the co-discoverer (in 1976 with Pierre Monceau) of “sliding charge density wave”, an unusual charge conduction mechanism in which the electronic charge density wave slides collectively in an applied electric field. His team has made many important contributions to the fields of superconductivity, magnetism and thermoelectrics. His experiments have shown that the rigidity of the superconducting wave function in cuprates collapses at the critical temperature, a scenario distinct from that in low-temperature superconductors. In ferromagnets, his findings helped ignite modern interest in how the Berry phase produces the anomalous Hall effect universally observed in ordinary ferromagnets as well as exotic spiral magnets bearing “skyrmion” excitations. In topological insulators, his team conducted experiments which successfully detected the current carried by surface topological electrons. Dr. Ong has been awarded the Kamerlingh Onnes Prize, and he is an elected member of the American Academy of Arts and Sciences and the National Academy of Sciences. Dr. Ong earned his PhD from the University of California in Berkeley.
