Quantum Phase Transitions and Fractional Quantized Anomalous Hall Insulators in Rhombohedral Graphene
Zach Hadjri, Xinlei Yue, Tonghang Han +10
Fractional quantum anomalous Hall effect (FQAHE) has been discovered in twisted MoTe and rhombohedral graphene/hBN moiré superlattices. Such van der Waals heterostructures feat…

Electromagnetic Response of a Half-Filled Chern Band near Topological Criticality
Xinlei Yue, Fabian Pichler, Michael Knap +1
We evaluate electromagnetic-response observables in a half-filled Chern band, across a topological phase transition between a composite Fermi liquid (CFL) and a Fermi liquid (FL) p…

Electronic Excitations in the Bulk of Fractional Quantum Hall States
Xinlei Yue, Ady Stern
We analyze electronic excitations (excitations generated by adding or removing one electron) in the bulk of fractional quantum Hall states in Jain sequence states, using composite…
