From linear to circular polarized light -- Floquet engineering in Kitaev-Heisenberg materials with Lissajous figures

TL;DR

This paper explores how Floquet engineering with arbitrary polarization, including complex Lissajous figures, affects $ ext{RuCl}_3$, bridging the gap between linear and circular polarization effects through perturbation theory.

Contribution

It introduces a comprehensive model for Floquet engineering with arbitrary polarization in Kitaev-Heisenberg materials, extending beyond traditional linear and circular cases.

Findings

Derived a perturbation theory model up to fourth-order

Bridged the gap between linear and circular polarization effects

Analyzed complex Lissajous figures and their influence

Abstract

This paper discusses Floquet engineering with arbitrary polarization in $\alpha$-RuCl$_3$. We describe the influence of arbitrary polarization and the limiting cases of linear and circular polarization. The corresponding model is derived via perturbation theory up to fourth-order. Starting from linear and circular polarization we bridge the gap between those two limiting cases. We then we study more complex Lissajous figures and general trends arising for them.
