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…

Floating Edge Bands in the Bernevig-Hughes-Zhang model with Altermagnetism
Yang-Yang Li, Song-Bo Zhang
Floating edge bands (FEB) have been identified in systems such as obstructed atomic insulators and layered nonsymmorphic semimetals, attracting considerable interest recently. Here…
