Moses Chan Hung-Wai () is a Chinese-American physicist who is Evan Pugh Professor at Pennsylvania State University. He was a postdoctoral associate at Duke University and has been a professor at Penn State University Park since 1979.
Through the years, Chan's work has spanned many diverse topics. For his numerous contributions to low-temperature physics, in 1996 he shared the prestigious Fritz London Memorial prize with Carl Wieman and Eric A. Cornell. He was elected a member of the National Academy of Sciences in 2000, and a fellow of the American Academy of Arts and Sciences in 2004.
Chan is known for the experimental discovery of evidence for a new supersolid quantum state of matter, predicted theoretically in 1969 by Alexander Andreev and Ilya Liftshitz, and its subsequent refutation. Other significant discoveries include the experimental observation of Critical Casimir effect and the experimental confirmation of 2D Ising model.
Born in Xi'an in 1946, he moved to Hong Kong in his childhood and completed his primary and secondary education in Yuen Long District. In 1967, Chan received his bachelor's degree from Bridgewater College in Virginia, United States. From 1969 to 1970, he taught at the University of Hong Kong.
