The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

When two sheets of graphene are stacked at a small twist angle, the resulting flat
superlattice minibands are expected to strongly enhance electron-electron interactions …

The importance of global band topology is unequivocally recognized in condensed matter
physics, and new states of matter, such as topological insulators, have been discovered …

The discovery of the quantum Hall (QH) effect led to the realization of a topological
electronic state with dissipationless currents circulating in one direction along the edge of a …

The quantum anomalous Hall effect is defined as a quantized Hall effect realized in a system
without an external magnetic field. The quantum anomalous Hall effect is a novel …

The “magnetoelectric effect” arises from the coupling between magnetic and electric
properties in materials. The Z 2 invariant of topological insulators (TIs) leads to a quantized …

Recent demonstrations of magnetization switching induced by in-plane current in heavy
metal/ferromagnetic heterostructures (HMFHs) have drawn great attention to spin torques …

The quantized version of the anomalous Hall effect has been predicted to occur in magnetic
topological insulators, but the experimental realization has been challenging. Here, we …

Topological insulators are bulk electronic insulators with symmetry-protected gapless modes
on their surfaces,,,,. Breaking time-reversal symmetry in these systems via ferromagnetism …
