Intervalley coherence and intrinsic spin-orbit coupling in rhombohedral trilayer graphene

Trevor Arp, Owen Sheekey, Haoxin Zhou +15

Rhombohedral graphene multilayers provide a clean and highly reproducible platform to explore the emergence of superconductivity and magnetism in a strongly interacting electron sy…

Realization of the Haldane Chern insulator in a moiré lattice

Wenjin Zhao, Kaifei Kang, Lizhong Li +7

The Chern insulator displays a quantized Hall effect without Landau levels. In a landmark paper in 1988, Haldane showed that a Chern insulator could be realized through complex nex…

Intrinsic spin Hall torque in a moire Chern magnet

C. L. Tschirhart, Evgeny Redekop, Lizhong Li +9

In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferrom…

Imaging orbital ferromagnetism in a moiré Chern insulator

C. L. Tschirhart, M. Serlin, H. Polshyn +8

Electrons in moiré flat band systems can spontaneously break time reversal symmetry, giving rise to a quantized anomalous Hall effect. Here we use a superconducting quantum interfe…

Electrical switching of magnetic order in an orbital Chern insulator

Hryhoriy Polshyn, Jihang Zhu, Manish A. Kumar +8

Magnetism typically arises from the joint effect of Fermi statistics and repulsive Coulomb interactions, which favors ground states with non-zero electron spin. As a result, contro…

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…
