Engineering electrically-switchable quantum anomalous Hall states by spin-orbit coupling
Maosen Qin, Ziwei Wang, Gyeongmin Kim +5
Nonvolatile gate-driven switching of quantum anomalous Hall (QAH) states in graphene moiré systems provides a promising route toward topological electronics based on chiral edge st…
Topological charge density waves at half-integer filling of a moiré superlattice
Hryhoriy Polshyn, Yuxuan Zhang, Manish A. Kumar +7
At partial filling of a flat band, strong electronic interactions may favor gapped states harboring emergent topology with quantized Hall conductivity. Emergent topological states…
The Future of the Correlated Electron Problem
A. Alexandradinata, N. P. Armitage, Andrey Baydin +44
A central problem in modern condensed matter physics is the understanding of materials with strong electron correlations. Despite extensive work, the essential physics of many of t…
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…
