Impurity-induced thermal crossover in fractional Chern insulators
Ke Huang, Sankar Das Sarma, Xiao Li
The recent experimental observation of fractional quantum anomalous Hall (FQAH) states in rhombohedral multilayer graphene has attracted significant attention. One of the most intr…
Fractional quantum anomalous Hall effect in rhombohedral multilayer graphene with a strong displacement field
Ke Huang, Sankar Das Sarma, Xiao Li
We investigate the fractional quantum anomalous Hall (FQAH) effect in rhombohedral multilayer graphene (RnG) in the presence of a strong applied displacement field. We first introd…
Self-consistent theory for the fractional quantum anomalous Hall effect in rhombohedral pentalayer graphene
Ke Huang, Xiao Li, Sankar Das Sarma +1
The fractional quantum anomalous Hall (FQAH) effect in rhombohedral pentalayer graphene (PLG) has attracted significant attention due to its potential for observing exotic quantum…
Pseudospin Polarization of Composite Fermions under Uniaxial Strain
Shuai Yuan, Jiaojie Yan, Ke Huang +6
A two dimensional system with extra degrees of freedom, such as spin and valley, is of great interest in the study of quantum phase transitions. The critical condition when a trans…
