WebJan 1, 2024 · A theory of the topological Hall effect (THE) in 2D systems with randomly located chiral spin textures is discussed. There are two different theoretical approaches valid in the two opposite limiting cases. The adiabatic approach is valid for a strong exchange interaction; it treats THE in terms of geometrical Berry phase and predicts a ... WebJan 7, 2024 · Notably, the chiral excitonic state gives rise to a quantum anomalous Hall conductance, providing an appealing interpretation of the observed anomalous Hall effect in kagome metals. Possible alternative realisations of the TvHS mechanism in bilayer materials are also discussed. We suggest that TvHS open up interesting possibilities for ...

The Hall-like … WebThe most popular explanation for the existence of chiral edge states is probably the following: in a magnetic field, electrons move in cyclotron orbits, and such such cyclotron orbits ensure electrons to move in a single direction at the edge. That is why the edge state is chiral. I think this picture is too classical.
