Quantum theory of the nonlinear Hall effect [PDF]

open access: yesNature Communications, 2021
The nonlinear Hall effect is a quantum phenomenon, in which two perpendicular currents induce a Hall voltage; however, previous theories for this effect has remained at the semi classical level.

Quantum Hall effect: from the drude conductivity model to the Chern-Simons field description

open access: yesRevista Brasileira de Ensino de Física, 2023
The goal of this article is to introduce the quantum Hall effect (QHE) from its classical roots to the quantum integer and fractional versions. This is a robust phenomenon with topological nature.
