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{…
Stable Topology in Exactly Flat Bands
Yan-Qi Li, Yi-Jie Wang, Pei-Han Lin +2
Topological flat bands (FBs) offer an ideal platform for realizing exotic topological phases and exploring quantum geometric effects, yet their realization with both exact flatness…
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…
Spin-Valley Anderson Impurity for Moiré Systems: Fermi Liquid, Pairing, and Pseudogap
Yi-Jie Wang, Geng-Dong Zhou, Hyunsung Jung +3
Recent experiments support that the magic-angle graphene can be modeled by a periodic array of correlated quantum impurities, immersed in a Dirac sea. This work analytically tackle…
Electron phonon coupling in the topological heavy fermion model of twisted bilayer graphene

Magic-angle twisted bilayer graphene (MATBG) exhibits correlated phenomena such as superconductivity and Mott insulating state related to the weakly dispersing flat band near the F…
Molecular Pairing in Twisted Bilayer Graphene Superconductivity
Yi-Jie Wang, Geng-Dong Zhou, Shi-Yu Peng +2
We propose a theory for how the weak phonon-mediated interaction (meV) wins over the prohibitive Coulomb repulsion (meV) and leads to…
