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…
Strongly Correlated Superconductivity in Twisted Bilayer Graphene: a Gutzwiller Study
Matthew Shu Liang, Yi-Jie Wang, Geng-Dong Zhou +2
We study strongly correlated superconductivity in magic-angle twisted bilayer graphene (MATBG) using a variational Gutzwiller wavefunction $\ket{Ψ_G} = \prod_{\vb{R}} \hat{P}_{\vb…
Fractional High-Chern Insulator in Twisted Rhombohedral Graphene
Zexu Li, Wenxuan Wang, Fajie Wang +9
The realization of fractional Chern insulators opens up the possibility of exploring fractionally charged excitations and anyonic statistics in the absence of a magnetic field. A c…
Field-induced asymmetric band flattening and ideal quantum geometry in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Size Wu +17
Rhombohedral graphene exhibits an exceptionally diverse array of correlated phases that depend sensitively on the displacement field. Compiling reported phases into a unified phase…
Chern number reversal and emergent superconductivity in rhombohedral graphene induced by in-plane magnetic fields
Xiaozhou Zan, Hangzhe Li, Jiawei Guo +11
Rhombohedral graphene with topological flat bands offers an ideal platform for realizing correlated and topological quantum phases. Here we investigate hBN aligned eight-layer rhom…
Programmable Quantum Anomalous Hall Insulator in Twisted Crystalline Flatbands
Wenxuan Wang, Yijie Wang, Zaizhe Zhang +8
The isospin flavors in condensed matters can be continuously broken, forming various symmetry-broken quantum states. In moiré crystals, the competition between different isospin c…
