SUMMARY:2/18/2021 Quantum Matter Seminar
DESCRIPTION:Speaker:  Xiao-Gang Wen (MIT) \nTitle: A solution to the chiral fermion problem \nAbstract: Motivated by the relation between anomaly and topological/SPT order in one higher dimension\, we propose a solution to the chiral fermion problem. In particular\, we find several sufficient conditions\, such that a chiral fermion field theory can be regularized by an interacting lattice model in the same dimension. We also discuss some related issues\, such as mass without mass term\, and why ‘topological’ phase transitions are usually not “topological” phase transitions.
