Intervalley-Coupled Twisted Bilayer Graphene from Substrate Commensuration
Bo-Ting Chen, Michael G. Scheer, Biao Lian
We show that intervalley coupling can be induced in twisted bilayer graphene (TBG) by aligning the bottom graphene layer with either of two types of commensurate insulating triangu…
Spectroscopy of the Fractal Hofstadter Energy Spectrum
Kevin P. Nuckolls, Michael G. Scheer, Dillon Wong +7
Hofstadter's butterfly, the predicted energy spectrum for non-interacting electrons confined to a two-dimensional lattice in a magnetic field, is one of the most remarkable fractal…
Correlated topological flat bands in rhombohedral graphite
Hongyun Zhang, Qian Li, Michael G. Scheer +22
Flat bands and nontrivial topological physics are two important topics of condensed matter physics. With a unique stacking configuration analogous to the Su-Schrieffer-Heeger (SSH)…
Electron phonon coupling in the topological heavy fermion model of twisted bilayer graphene
Yi-Jie Wang, Geng-Dong Zhou, Biao Lian +1
On flat bands of the magic-angle twisted bilayer graphene, exotic correlation physics unfolds. Phonons, through mediating an effective electron-electron interaction, can play a cru…
Strain and twist angle driven electronic structure evolution in twisted bilayer graphene
Jiawei Yu, Guihao Jia, Qian Li +14
In twisted bilayer graphene (TBG) devices, local strains frequently coexist and intertwine with the twist-angle-dependent moiré superlattice, significantly influencing the electron…
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…
