Research Interest
Yunqin Zheng works on a range of topics in quantum field theories and condensed matter theories. His recent research focuses on generalized symmetries and anomalies in field theories and lattice models in diverse dimensions. These symmetries lead to various new insights on renormalization group flows, and provide new organization principles local operators, defects, interfaces, as well as quantum phases of matters and their phase transitions.
