Fractional High-Chern Insulator in Twisted Rhombohedral Graphene
Zexu Li, Wenxuan Wang, Fajie Wang +9
The realization of fractional Chern insulators opens up the possibility of exploring fractionally charged excitations and anyonic statistics in the absence of a magnetic field. A c…
Correlated Charge Density Wave Insulators in Chirally Twisted Triple Bilayer Graphene
Wenxuan Wang, Gengdong Zhou, Wenlu Lin +16
Electrons residing in flat-band system can play a vital role in triggering spectacular phenomenology due to relatively large interactions and spontaneous breaking of different dege…
Correlated insulators and charge density wave states in chirally twisted triple bilayer graphene
Geng-Dong Zhou, Yi-Jie Wang, Wen-Xuan Wang +2
Motivated by recent experimental observations of displacement-field-tuned correlated insulators at integer and half-integer fillings in chirally twisted triple bilayer graphene (CT…
Tunable Fractional Chern Insulators in Rhombohedral Graphene Superlattices
Jian Xie, Zihao Huo, Xin Lu +11
Fractional Chern insulators (FCIs) showing a transport effect with fractionally quantized Hall plateaus emerging under zero magnetic field, provide a radically new opportunity to e…
