Similarity of Fractional Chern Insulators to Fractional Quantum Hall States: Moiré-Enhanced Gaps and Excitation-Spectrum Correspondence
feeds.aps.org · By Siddhartha Sarkar, Yitong Zhang & Kai Sun ·
Author(s): Siddhartha Sarkar, Yitong Zhang, and Kai Sun The excitation spectrum of fractional Chern insulators is identical to their fractional quantum Hall counterparts except for an enhancement factor, making it possible to predict their excitation spectrum from the…
