Guangzhao Zhou is renowned for his discovery of PCAC — partial conservation of axial current —widely considered to be one of the most important contributions to particle physics. PCAC is key to understanding the interactions of fundamental particles known as pions. In statistical mechanics and condensed matter physics, Guangzhao’s work on Green’s function has applications that include laser and plasma physics.
In addition, Guangzhao also proved an important theorem relating to the ratios of the products of particle decay and a concept known as charge–parity–time (CPT) invariance. He has also made important contributions to detonation physics, radiation hydrodynamics and computing methods in mechanics.
Guangzhao also played a leading role in helping Chinese scientists to prepare for a knowledge-based economy. He is widely respected for his work to promote international science exchange and inspire young scientists. His work has been recognised by the award of honorary degrees from the City University of New York, McGill University in Canada, and the University of Hong Kong. Asteroid 3462 Zhouguangzhao is named in his honour.
