Universality of Energy-Space Entanglement in Quantum Impurity Models
Geng-Dong Zhou, Zhi-Da Song
Entanglement entropy (EE) is commonly studied using real-space bipartitions. We show that, in quantum impurity models, an energy-space bipartition, equivalent to the momentum-space…
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…
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{…
Bosonization Solution to Spin-Valley Kondo Problem: Finite-Size Spectrum and Renormalization Group Analysis
Yi-Jie Wang, Geng-Dong Zhou, Hyunsung Jung +3
Spin-valley Anderson impurities (SVAIM) with (anti-)Hund's splitting provide a natural explanation to the origin of pairing potential and pseudogap in the magic-angle graphene. In…
