Vacancy-driven topological transition of a Chern insulator
Peize Ding, Raquel Queiroz
We develop a microscopic description of the strong-disorder transition in a Chern insulator using the in-gap ring states bound to individual vacancies. Using Green's function forma…

Composite Fermion Theory of Fractional Chern Insulators in Rhombohedral Graphene
Peize Ding, Andrew J. Millis, Yongxin Zeng
The experimental observation of the fractional quantum anomalous Hall effect in rhombohedral graphene multilayers has raised questions about the nature of the fractional Chern insu…
