Consistent symmetry breaking and topological phases
Yuezhao Li, Guo Chuan Thiang
The paper studies operators that are invariant under a symmetry group and shows that their equivariant indices must remain consistent when the symmetry is reduced to a finite‑index…
Universality of Energy-Space Entanglement in Quantum Impurity Models
Geng-Dong Zhou, Zhi-Da Song
The paper investigates entanglement entropy defined by an energy‑space bipartition in quantum impurity models, showing universal constant values tied to topological edge modes and…
Interaction-induced sign reversal of the orbital magnetic susceptibility in Chern insulators
Ke Huang, Xiao Li
The paper shows that electron interactions can reverse the sign of orbital magnetic susceptibility in Chern insulators, using a finite‑field Hartree‑Fock framework with a reverse P…
On -parastatistics I: Foundation
Zhiyuan Wang, Kaden R. A. Hazzard
The paper builds a theoretical framework for R‑parastatistics, introducing local observables that can distinguish R‑paraparticles and describing how such particles could arise as q…
Time-Reversal Invariant Topological Photonic Alloy
Feng Ruili, Qu Tiantao, Wu Xianbin +4
The paper demonstrates that local symmetry breaking via random doping in a photonic alloy can induce quantum spin Hall and quantum valley Hall topological phases without global str…
Monopole Spin Density Wave States in Magnetic Weyl Semimetals
Xi Luo
The paper proposes and analyzes monopole spin density wave states in magnetic Weyl semimetals, showing how particle‑hole pairing between same‑chirality Weyl nodes leads to topologi…
