Gauging (3+1)-dimensional topological phases: an approach from surface theories
Xiao Chen, Apoorv Tiwari, Chetan Nayak +1
We discuss several bosonic topological phases in (3+1) dimensions enriched by a global symmetry, and gauging the symmetry. More specifically, followin…

From orbifolding conformal field theories to gauging topological phases
Xiao Chen, Abhishek Roy, Jeffrey C. Y. Teo +1
Topological phases of matter in (2+1) dimensions are commonly equipped with global symmetries, such as electric-magnetic duality in gauge theories and bilayer symmetry in fractiona…

Anomaly Manifestation of Lieb-Schultz-Mattis Theorem and Topological Phases
Gil Young Cho, Chang-Tse Hsieh, Shinsei Ryu
The Lieb-Schultz-Mattis (LSM) theorem dictates that emergent low-energy states from a lattice model cannot be a trivial symmetric insulator if the filling per unit cell is not inte…
