Untwisting moiré physics: Almost ideal bands and fractional Chern insulators in periodically strained monolayer graphene
Qiang Gao, Junkai Dong, Patrick Ledwith +2
Moiré systems have emerged in recent years as a rich platform to study strong correlations. Here, we will discuss a simple, experimentally feasible setup based on periodically stra…

Exact Many-Body Ground States from Decomposition of Ideal Higher Chern Bands: Applications to Chirally Twisted Graphene Multilayers
Junkai Dong, Patrick J. Ledwith, Eslam Khalaf +2
Motivated by the higher Chern bands of twisted graphene multilayers, we consider flat bands with arbitrary Chern number with ideal quantum geometry. While bands differ fr…

Dirac electron under periodic magnetic field: Platform for fractional Chern insulator and generalized Wigner crystal
Junkai Dong, Jie Wang, Liang Fu
We propose a platform for flat Chern band by subjecting two-dimensional Dirac materials -- such as graphene and topological insulator thin films -- to a periodic magnetic field, wh…
