Designing topology and fractionalization in narrow gap semiconductor films via electrostatic engineering
Tixuan Tan, Aidan P. Reddy, Liang Fu +1
We show that topological flat minibands can be engineered in a class of narrow gap semiconductor films using only an external electrostatic superlattice potential. We demonstrate t…

Fractional Chern mosaic in supermoiré graphene
Yves H. Kwan, Tixuan Tan, Trithep Devakul
We propose the realization of a fractional Chern mosaic: a state characterized by a spatially varying topological order. This state is enabled by a separation of length scales that…
