# Magnus Hall Effect

## TL;DR

This paper predicts a novel linear response Hall effect in time-reversal-invariant systems caused by a quantum Magnus effect, linking the Hall response to Berry curvature distribution without magnetic fields.

## Contribution

It introduces the concept of the Magnus Hall effect, a new type of Hall response arising from self-rotating electron wavepackets in electric fields, expanding understanding of Hall phenomena.

## Key findings

- Magnus Hall conductance relates to Berry curvature on the Fermi surface
- The effect occurs at zero magnetic field in time-reversal-invariant systems
- The phenomenon is described in the ballistic transport limit

## Abstract

A new type of linear response Hall effect is predicted in time-reversal-invariant systems with built-in electric field at zero magnetic field. The Hall response results from a quantum Magnus effect where a self-rotating Bloch electron wavepacket moving under electric field develops an anomalous velocity in the transverse direction. We show that in the ballistic limit the Magnus Hall conductance measures the distribution of Berry curvature on the Fermi surface.
