The Hall effect, in which a current flows perpendicular to an electrical bias, has been
prominent in the history of condensed matter physics. Appearing variously in classical …

The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

Magnetism is one of the largest, most fundamental, and technologically most relevant fields
of condensed-matter physics. Traditionally, two basic magnetic phases have been …

The anomalous Hall effect (AHE) occurs in solids with broken time-reversal symmetry,
typically in a ferromagnetic phase, as a consequence of spin-orbit coupling. Experimental …

In ferromagnets, the spontaneous magnetization bears the Hall effect through the relativistic
spin-orbit interaction. Similar effects also occur in thermoelectric and thermal transport …

Direct measurements of spin fluctuations are becoming the mainstream approach for studies
of complex condensed matter, molecular, nuclear, and atomic systems. This review covers …

We demonstrate that the Berry curvature monopole of nonmagnetic two-dimensional spin-
3/2 holes leads to a novel Hall effect linear in an applied in-plane magnetic field B∥ …

In solid state conductors, linear response to a steady electric field is normally dominated by
Bloch state occupation number changes that are correlated with group velocity and lead to a …

Recent work has extended topological band theory to open, non-Hermitian Hamiltonians,
yet little is understood about how non-Hermiticity alters the topological quantization of …

The anomalous Hall effect arises in systems with both spin-orbit coupling and
magnetization. Generally, there are three mechanisms contributing to anomalous Hall …
