-type Lieb-Schultz-Mattis anomalies, deconfined quantum critical points, and non-invertible symmetry breaking
Hao-Ran Zhang, Hanlin Lin, Shuo Yang +1
We study deconfined quantum critical points (DQCP) associated with Lieb-Schultz-Mattis (LSM) anomalies in one-dimensional spin chains. Our starting point is a structural characteri…
Bridging Microscopic Constructions and Continuum Topological Field Theory of Three-Dimensional Non-Abelian Topological Order
Yizhou Huang, Zhi-Feng Zhang, Qing-Rui Wang +1
Continuum field-theoretical descriptions of topological order are often constructed at long distances without direct reference to microscopic short-distance realizations, guided in…
Non-invertible symmetries and mixed anomalies from conserved current construction in (3+1)D twisted topological quantum field theories
Zhi-Feng Zhang, Yizhou Huang, Qing-Rui Wang +1
We develop a current-based construction of generalized symmetries in D twisted topological quantum field theories (TQFTs), focusing on intrinsically non-invertible high…
Classification of Interacting Topological Crystalline Superconductors in Three Dimensions and Beyond
Shang-Qiang Ning, Xing-Yu Ren, Qing-Rui Wang +2
Although classification for free-fermion topological superconductors (TSC) is established, systematically understanding the classification of 3D interacting TSCs remains difficult,…
Systematic Construction of Interfaces and Anomalous Boundaries for Fermionic Symmetry-Protected Topological Phases
Kevin Loo, Qing-Rui Wang
We use the pullback trivialization technique to systematically construct gapped interfaces and anomalous boundaries for fermionic symmetry-protected topological (FSPT) states by ex…
