Photogalvanic effect in few layer graphene
Zhaohang Li, Kainan Chang, Haoyu Li +4
We systematically investigate the nonlinear photogalvanic effect in few-layer graphene with various stacking orders, including AA- and AB-stacked bilayers, and AAA-, ABA-, and ABC-…
Incommensurate-Stabilized Fractional Chern Insulator in Alternating Twisted Trilayer Graphene
Moru Song, Kai Chang
Fractional Chern insulators (FCIs) typically emerge in topological flat bands and are regarded as lattice analogs of fractional quantum Hall states. Conventionally, the flat-band w…
Fractional Chern Insulators Transition in Non-ideal Flat Bands of Twisted Mono-bilayer Graphene
Moru Song, Kai Chang
Fractional Chern insulators (FCIs) in ideal flat bands with Chern number are commonly understood as color-entangled states constructed from copies of the lowest Landau leve…
Anomalous Rashba spin-orbit interaction in InAs/GaSb quantum wells
J. Li, Kai Chang, G. Q. Hai +1
We investigate theoretically the Rashba spin-orbit interaction in InAs/GaSb quantum wells(QWs). We find that the Rashba spin-splitting (RSS) depends sensitively on the thickness of…
