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…
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 num…
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}_{…
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…
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…
C-R-T Fractionalization, Fermions, and Mod 8 Periodicity
Zheyan Wan, Juven Wang, Shing-Tung Yau +1
Charge conjugation (C), mirror reflection (R), time reversal (T), and fermion parity are basic discrete spacetime and internal symmetries of the Dirac fermions. In t…
Superconductivity from Doping Symmetric Mass Generation Insulators: Application to LaNiO under Pressure
Da-Chuan Lu, Miao Li, Zhao-Yi Zeng +4
We investigate the bilayer nickelates as a platform to realize the symmetric mass generation (SMG) insulator, a featureless Mott insulator that arises due to the Lieb-Schultz-Matti…
Categorical Symmetry of the Standard Model from Gravitational Anomaly
Pavel Putrov, Juven Wang
In the Standard Model, some combination of the baryon and lepton number symmetry is free of mixed anomalies with strong and electroweak $su(3) \times su(2) \times u…
Definition and Classification of Fermi Surface Anomalies
Da-Chuan Lu, Juven Wang, Yi-Zhuang You
We propose that the Fermi surface anomaly of symmetry group in any dimension is universally classified by -symmetric interacting fermionic symmetry-protected topological (SP…
Strong CP Problem and Symmetric Mass Solution
Juven Wang
We propose a novel solution to the Strong CP problem -- to explain why SU(3) strong force has a nearly zero theta angle for the 4d Standard Model (SM). The new i…
Fermi Surface Symmetric Mass Generation
Da-Chuan Lu, Meng Zeng, Juven Wang +1
Symmetric mass generation is a novel mechanism to give gapless fermions a mass gap by non-perturbative interactions without generating any fermion bilinear condensation. The previo…
Flavor Hierarchy from Smooth Confinement
Yuta Hamada, Juven Wang
We present a model to explain the Standard Model flavor hierarchy. Our model is based on explicit smooth confinement (namely confinement without chiral symmetry breaking in a super…
CT or P Problem and Symmetric Gapped Fermion Solution
Juven Wang
An analogous "Strong CP problem" is identified in a toy model in 2-dimensional spacetime: a general 1+1d abelian U(1) anomaly-free chiral fermion and chiral gauge theory with a gen…
Symmetric Mass Generation
Juven Wang, Yi-Zhuang You
The most well-known mechanism for fermions to acquire a mass is the Nambu-Goldstone-Anderson-Higgs mechanism, i.e. after a spontaneous symmetry breaking, a bosonic field that coupl…
Proton Stability: From the Standard Model to Beyond Grand Unification
Juven Wang, Zheyan Wan, Yi-Zhuang You
A proton is known for its longevity, but what is its lifetime? While many Grand Unified Theories predict the proton decay with a finite lifetime, we show that the Standard Model (S…
Deconfined Quantum Criticality among Grand Unified Theories
Yi-Zhuang You, Juven Wang
This article overviews the recent developments in applying the idea of deconfined quantum criticality in condensed matter physics to understand quantum phase transitions among gran…
Symmetric Mass Generation in the 1+1 Dimensional Chiral Fermion 3-4-5-0 Model
Meng Zeng, Zheng Zhu, Juven Wang +1
Lattice regularization of chiral fermions has been a long-standing problem in physics. In this work, we present the density matrix renormalization group (DMRG) simulation of the 3-…
Cobordism and Deformation Class of the Standard Model
Juven Wang, Zheyan Wan, Yi-Zhuang You
't Hooft anomalies of quantum field theories (QFTs) with an invertible global symmetry G (including spacetime and internal symmetries) in a d spacetime are known to be classifie…
3+1d Boundaries with Gravitational Anomaly of 4+1d Invertible Topological Order for Branch-Independent Bosonic Systems
Zheyan Wan, Juven Wang, Xiao-Gang Wen
We study bosonic systems on a spacetime lattice defined by path integrals of commuting fields. We introduce branch-independent bosonic (BIB) systems, whose path integral is indepen…
Gauge Enhanced Quantum Criticality Between Grand Unifications: Categorical Higher Symmetry Retraction
Juven Wang, Yi-Zhuang You
Prior work [arXiv:2106.16248] shows that the Standard Model (SM) naturally arises near a gapless quantum critical region between Georgi-Glashow (GG) and Pati-Salam (PS) $su…
