Simulating high-temperature superconductivity in moiré WSe2
Yiyu Xia, Zhongdong Han, Jiacheng Zhu +6
The emergence of high transition temperature (Tc) superconductivity in strongly correlated materials remains a major unsolved problem in physics. High-Tc materials, such as cuprate…
Correlated states controlled by tunable van Hove singularity in moiré WSe2
Patrick Knüppel, Jiacheng Zhu, Yiyu Xia +7
Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topolo…
Continuous Mott transition in semiconductor moiré superlattices
Tingxin Li, Shengwei Jiang, Lizhong Li +9
The evolution of a Landau Fermi liquid into a nonmagnetic Mott insulator with increasing electronic interactions is one of the most puzzling quantum phase transitions in physics. T…
Charge-order-enhanced capacitance in semiconductor moiré superlattices
Tingxin Li, Jiacheng Zhu, Yanhao Tang +5
Van der Waals moiré materials have emerged as a highly controllable platform to study the electronic correlation phenomena. In particular, robust correlated insulating states have…
Intrinsic quantized anomalous Hall effect in a moiré heterostructure
M. Serlin, C. L. Tschirhart, H. Polshyn +6
We report the observation of a quantum anomalous Hall effect in twisted bilayer graphene showing Hall resistance quantized to within .1\% of the von Klitzing constant at ze…
