Unconventional Orbital Magnetism in Graphene-based Fractional Chern Insulators
Jian Xie, Zaizhe Zhang, Xi Chen +11
Orbital magnetism in graphene originates from correlation-driven spontaneous valley symmetry breaking1-7. It can lead to various anomalous transport phenomena such as integer and f…
Stable Real-Space Invariants and Topology Beyond Symmetry Indicators
Yoonseok Hwang, Vaibhav Gupta, Frank Schindler +4
We introduce stable real-space invariants (SRSIs), topological invariants defined from adiabatic deformations between Wannier states, generalizing previously discovered local and c…
Projected and Solvable Topological Heavy Fermion Model of Twisted Bilayer Graphene
Haoyu Hu, Zhi-Da Song, B. Andrei Bernevig
We investigate the topological heavy-fermion (THF) model of magic-angle twisted bilayer graphene (MATBG) in the projected limit, where only the flat bands are present in the low-en…
Intrinsic (Axion) Statistical Topological Insulator
Xi Chen, Fa-Jie Wang, Zhen Bi +1
Ensembles that respect symmetries on average exhibit richer topological states than those in pure states with exact symmetries, leading to the concept of average symmetry-protected…
