Gradient-based optimization of non-Abelian fractional quantum states in patterned superlattices
Yifei Guan, Lichen Yu, Zizhuang Liu +2
The realization of fractional Chern insulator (FCI) states in moiré heterostructures has attracted intense interest in the study of correlated topological states. So far, most expe…
Electronic states at twist stacking faults in rhombohedral graphite
Xiaoqian Liu, Yifei Guan, Oleg V. Yazyev
Flat bands in graphitic materials emerged as a platform for realizing tunable correlated physics. As a nodal-line semimetal, rhombohedral graphite features flat drumhead surface st…
Strongly correlated Hofstadter subbands in minimally twisted bilayer graphene
Cheng Shen, Yifei Guan, Davide Pizzirani +7
Moiré superlattice in twisted bilayer graphene has been proven to be a versatile platform for exploring exotic quantum phases. Extensive investigations have been invoked focusing…
Renormalization group of topological scattering networks
Zhe Zhang, Yifei Guan, Junda Wang +5
Exploring and understanding topological phases in systems with strong distributed disorder requires developing fundamentally new approaches to replace traditional tools such as top…
