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…
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…
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…
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…
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…
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-…
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…
