Interaction-driven Roton Condensation in C = 2/3 Fractional Quantum Anomalous Hall State
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +2
The interplay of topological order and charge order exhibits rich physics. Recent experiments that succesfully realized the frational quantum anomalous Hall (FQAH) effect in twiste…
From Fractional Quantum Anomalous Hall Smectics to Polar Smectic Metals: Nontrivial Interplay Between Electronic Liquid Crystal Order and Topological Order in Correlated Topological Flat Bands
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +2
Symmetry-breaking orders can not only compete with each other, but also be interwined, and the interwined topological and symmetry-breaking orders make the situation more intriguin…
Thermodynamic Response and Neutral Excitations in Integer and Fractional Quantum Anomalous Hall States Emerging from Correlated Flat Bands
Hongyu Lu, Bin-Bin Chen, Han-Qing Wu +2
Integer and fractional Chern insulators have been extensively explored in correlated flat band models. Recently, the prediction and experimental observation of fractional quantum a…
An integral algorithm of exponential observables for interacting fermions in quantum Monte Carlo simulation
Xu Zhang, Gaopei Pan, Bin-Bin Chen +2
Exponential observables, formulated as where is an extensive quantity, play a critical role in study of quantum many-body systems, examp…
