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…
Heavy Fermions as an Efficient Representation of Atomistic Strain and Relaxation in Twisted Bilayer Graphene
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru Călugăru +5
Although the strongly interacting flat bands in twisted bilayer graphene (TBG) have been approached using the minimal Bistritzer-MacDonald (BM) Hamiltonian, there is mounting evide…
Topological Heavy Fermion Principle For Flat (Narrow) Bands With Concentrated Quantum Geometry
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru Călugăru +8
We propose a general principle for the low-energy theory of narrow bands with concentrated Berry curvature and Fubini-Study metric in the form of a map to Anderson-"+" models compo…
