Abstract
Charge conjugation (C), Parity (P), and Time-reversal (T) are three discrete transformations that act on particles and fields. C-P-T-fractionalization is the discrete group generated by C, P, T, and the Fermion parity F. In this talk, I will determine the C-P-T-fractionalization for spin 1/2 Lorentz spinors in all dimensions and explain the relations between the C-P-T-fractionalization in different dimensions. This is my joint work in progress with Juven Wang and Prof. Shing-Tung Yau.
Speaker Intro
I obtained my Bachelor's and Ph.D. degrees from the University of Science and Technology of China. Before my current position as an assistant professor at BIMSA, I was a postdoc at Yau Mathematical Sciences Center, Tsinghua University. My research interests lie in using topological methods (cobordism) to study theoretical physics (anomaly).
