Nai Phuan Ong (born 10 September 1948 in Penang, Malaysia) is an American experimental physicist, specializing in "condensed matter physics focusing on topological insulators, Dirac/Weyl semimetals, superconductors and quantum spin liquids."[1]
Biography
Nai Phuan Ong was born in Penang, Malaysia to parents of Chinese origin on 10 September 1948.[2] He grew up speaking a Chinese dialect with his parents and English with his seven siblings.[2] As a youth, he attended Saint Xaviers Institution, run by the Christian Brothers, where classes were taught in English.[2] His interest in science was spurred by his sister's library books; he started going to the library himself at the age of ten and read books about science and airplanes, fascinated to learn how they fly. He started building toy airplanes and copying drawings of turbine blades and pistons in jet engines.[2]
Ong immigrated to the United States with his family in 1967. He won a scholarship to Columbia College,[3] the oldest undergraduate college of Columbia University, and graduated from there in 1971 with a B.A. in physics. He went on to complete a Ph.D., in 1976,[4] under the direction of Alan Portis, from the University of California, Berkeley. At the University of Southern California, Ong was an assistant professor from 1976 to 1982, an associate professor 1982 to 1984, and a full professor in 1985. He joined the faculty at Princeton University as the first Asian professor in 1985.[2] In 2003, he was appointed to the Eugene Higgins Professorship of Physics,[5] which he continues to hold. Ong was a member of the editorial board of the journal Science from January 2012 to February 2014.
He has been the advisor for many doctoral students, including Harold Y. Hwang, and many post-docs, including Kathryn Moler.[6]
In 1982 Ong married Delicia Lai (born 1960).
Research
In the 1970s and 1980s Ong did important research on charge-density waves.[7][8] After the discovery of high temperature superconductivity, Ong worked on transport phenomena in cuprate semiconductors.[9][10] In recent years, Ong has done research on Dirac and Weyl semimetals, the thermal Hall effect, and topological superconductors.[11]
In 2000, Ong’s group found that the cuprate pair condensate survives to temperatures high above TC. The loss of superconductivity at TC arises from the collapse of phase rigidity rather than the closing of a gap. However, its existence is betrayed by a large Nernst effect and a large orbital diamagnetism. In topological matter, Ong with Bob Cava detected (2010) surface Dirac states in the topological insulator Bi2Te3 by measuring quantum oscillations in a tilted magnetic field. In 2014, Ong and Cava obtained evidence for the predicted "chiral anomaly" in the Dirac semimetals Na3Bi and GdPtBi. In several frustrated quantum magnets, Ong’s group has found that spin excitations produce a large thermal Hall current despite being strictly charge-neutral.[1]
