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

Abstract

This paper discusses Floquet engineering with arbitrary polarization in $\hat{I}\pm$-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.
