Bound states of anyons: a geometric quantization approach
Qingchen Li, Pavel A. Nosov, Taige Wang +1
The question of anyon interactions and their possible binding plays a key role in the physics of fractional quantum Hall states. Here, we introduce a controlled and scalable approa…

Anyon Dispersion in Aharonov-Casher Bands and Implications for Twisted MoTe
Zihan Yan, Qingchen Li, Tomohiro Soejima +1
The discovery of fractional quantum anomalous Hall (FQAH) states in two-dimensional heterostructures has opened the door to realizing phases of dispersing anyons. Here, we develop…

Constraints on real space representations of Chern bands
Qingchen Li, Junkai Dong, Patrick J. Ledwith +1
A Chern band is characterized by a Wannier obstruction indicating the absence of a basis of complete, orthogonal, and exponentially-localized states. Here, we study the properties…
