Boundary topological orders of (4+1)d fermionic SPT states
Meng Cheng, Juven Wang, Xinping Yang
We investigate (3+1)d topological orders in fermionic systems with an anomalous symmetry, where its subgroup is the fermi…
Anomalous (3+1)d Fermionic Topological Quantum Field Theories via Symmetry Extension
Zheyan Wan, Juven Wang
Discrete finite-group global symmetries may suffer from nonperturbative 't-Hooft anomalies. Such global anomalies can be canceled by anomalous symmetry-preserving topological quant…
Quantum Many-Body Lattice C-R-T Symmetry: Fractionalization, Anomaly, and Symmetric Mass Generation
Yang-Yang Li, Juven Wang, Yi-Zhuang You
Charge conjugation (C), mirror reflection (R), and time reversal (T) symmetries, along with internal symmetries, are essential for massless Majorana and Dirac fermions. These symme…
C-R-T Fractionalization in the First Quantized Hamiltonian Theory
Yang-Yang Li, Zheyan Wan, Juven Wang +2
Recent research has revealed that the CRT symmetry for fermions exhibits a fractionalization distinct from the $\mathbb{Z}_2^{\mathcal{C}}\times\mathbb{Z}_2^{\mathcal{R}}\times\mat…
Topological Responses of the Standard Model Gauge Group
Zheyan Wan, Juven Wang, Yi-Zhuang You
The local Lie algebra of the Standard Model (SM) is , yet its global gauge group, SU(3)SU(2)U(1)/$\mathbb{Z}_{…
Topological Quantum Dark Matter via Global Anomaly Cancellation
Juven Wang
Standard Model (SM) with 15 Weyl fermions per family (lacking the 16th, the sterile right-handed neutrino ) suffers from mixed gauge-gravitational anomalies tied to baryon nu…
