Extended Fractional Chern Insulators Near Half Flux in Twisted Bilayer Graphene Above the Magic Angle
Joe Finney, Aaron L. Sharpe, Linsey K. Rodenbach +7
Fractional Chern insulators (FCIs) -- the lattice analog of fractional quantum Hall states -- form as fractionalized quasiparticles emerge in a partially-filled Chern band. This fr…
Observation of giant nonlinear Hall conductivity in Bernal bilayer graphene
Dmitry V. Chichinadze, Naiyuan James Zhang, Jiang-Xiazi Lin +6
In a system of two-dimensional electrons, a combination of broken symmetry, interactions, and nontrivial topology can conspire to give rise to a nonlinear transport regime, where e…
Strongly interacting Hofstadter states in magic-angle twisted bilayer graphene
Minhao He, Xiaoyu Wang, Jiaqi Cai +8
Magic-angle twisted bilayer graphene (MATBG) hosts a multitude of strongly correlated states at partial fillings of its flat bands. In a magnetic field, these flat bands further ev…
Interacting phase diagram of twisted bilayer MoTe in magnetic field
Minxuan Wang, Xiaoyu Wang, Oskar Vafek
We study electron-electron interaction induced states of twisted bilayer MoTe in an out-of-plane magnetic field near one hole per moiré unit cell filling. The 3D…
