Quantized Landau-level crossing checkerboard in large-angle twisted graphene
Baojuan Dong, Kai Zhao, Kenji Watanabe +6
When charge transport occurs under conditions like topological protection or ballistic motion, the conductance of low-dimensional systems often exhibits quantized values in units o…
Topological Chiral Superconductivity Mediated by Intervalley Antiferromagnetic Fluctuations in Twisted Bilayer WSe
Wei Qin, Wen-Xuan Qiu, Fengcheng Wu
Motivated by the recent observations of superconductivity in twisted bilayer WSe (tWSe), we theoretically investigate the superconductivity driven by electronic mechanism.…
Observation of Ferromagnetic Phase in the Second Moiré Band of Twisted MoTe2
Liheng An, Haiyang Pan, Wen-Xuan Qiu +13
Flat bands and electron correlation in moiré lattices give rise to many exotic phases, including Mott insulators, superconductivity, and topological states. Within the first moiré…
Quantum Geometry Probed by Chiral Excitonic Optical Response of Chern Insulators
Wen-Xuan Qiu, Fengcheng Wu
We theoretically derive the sum rule for the negative first moment of the absorptive optical conductivity with excitonic effects and establish its connection to the quantum weight…
Tunable superconductivity in electron- and hole-doped Bernal bilayer graphene
Chushan Li, Fan Xu, Bohao Li +11
Graphene-based, high quality two-dimensional electronic systems have emerged as a highly tunable platform for studying superconductivity. Specifically, superconductivity has been o…
Variational Mapping of Chern Bands to Landau Levels: Application to Fractional Chern Insulators in Twisted MoTe
Bohao Li, Fengcheng Wu
We present a theoretical study of mapping between Chern bands and generalized Landau levels in twisted bilayer MoTe (MoTe), where fractional Chern insulators down to zer…
