Abstract Transverse current due to Berry curvature in phase space is formulated based on the Boltzmann equations with semiclassical of motion for an electron wave packet. It shown that Hall effect absent because contributions from “anomalous velocity” and “effective Lorentz force” are completely cancelled out.

Abstract The layer Hall effect describes electrons spontaneously deflected to opposite sides at different layers, which has been experimentally reported in the MnBi2Te4 thinfilms under perpendicular electric fields [Gao et al., Nature 595, 521 (2021)]. Here, beyond scenario of $\mathcal {PT}$-symmetry breaking experiment, we reveal a universal origin terms so-called hidden Berry curvature, as w...

Plasmons, the collective oscillations of interacting electrons, possess emergent properties that dramatically alter the optical response of metals. We predict the existence of a new class of plasmons-chiral Berry plasmons (CBPs)-for a wide range of 2D metallic systems including gapped Dirac materials. As we show, in these materials the interplay between Berry curvature and electron-electron int...
