Analytical solution for the relaxed atomic configuration of twisted bilayer graphene including heterostrain
Jian Kang, Oskar Vafek
Continuum atomic relaxation models for twisted bilayer graphene involve minimization of the sum of intralayer elastic energy and interlayer adhesion energy. The elastic energy favo…
Theory of correlated Chern insulators in twisted bilayer graphene
Xiaoyu Wang, Oskar Vafek
Magic-angle twisted bilayer graphene is the best studied physical platform featuring moire potential induced narrow bands with non-trivial topology and strong electronic correlatio…
Fractional Chern Insulators vs. Non-Magnetic States in Twisted Bilayer MoTe
Jiabin Yu, Jonah Herzog-Arbeitman, Minxuan Wang +3
Fractionally filled Chern bands with strong interactions may give rise to fractional Chern insulator (FCI) states, the zero-field analogue of the fractional quantum Hall effect. Re…
Topological heavy fermions in magnetic field
Keshav Singh, Aaron Chew, Jonah Herzog-Arbeitman +2
The recently introduced topological heavy fermion model (THFM) provides a means for interpreting the low-energy electronic degrees of freedom of the magic angle twisted bilayer gra…
Revisiting Bloch electrons in magnetic field: Hofstadter physics via hybrid Wannier states
Xiaoyu Wang, Oskar Vafek
We revisit the Hofstadter butterfly for a subset of topologically trivial Bloch bands arising from a continuum free electron Hamiltonian in a periodic lattice potential. We employ…
Electronic anisotropy in magic-angle twisted trilayer graphene
Naiyuan J. Zhang, Yibang Wang, Kenji Watanabe +3
Due to its potential connection with nematicity, electronic anisotropy has been the subject of intense research effort on a wide variety of material platforms. The emergence of spa…
