Exciton-roton mode in moiré fractional Chern insulators
Xiaoyang Shen, Zijian Zhou, Ruiping Guo +4
Moiré fractional Chern insulators (FCIs) are a novel class of quantum matter that realizes fractional quantum Hall (FQH) physics in zero magnetic field and provides a platform for…

Magnetic-field-tunable cyclotron hyperbolic polaritons
Zijian Zhou, Ran Jing, Heng Wang +3
Hyperbolic polaritons are conventionally associated with structural anisotropy or phononic Reststrahlen bands. Here, we predict a new class of hyperbolic polaritons arising from ma…

Quantum Metric-induced Oscillations in Flat Bands
Hui Zeng, Zijian Zhou, Wenhui Duan +1
The transport of Bloch electrons under strong fields is traditionally understood through two mechanisms: intraband Bloch oscillations and interband Zener tunneling. Here, we propos…
