Comparing the influence of Floquet dynamics in various Kitaev-Heisenberg materials

P Strobel, M Daghofer - Physical Review B, 2022‏ - APS
In this paper we examine the possibility of Floquet engineering in the three candidate Kitaev
materials Na 2 IrO 3, α-Li 2 IrO 3, and α-RuCl 3. We derive an effective Floquet Hamiltonian …

Symmetry-protected difference between spin Hall and anomalous Hall effects of a periodically driven multiorbital metal

N Arakawa, K Yonemitsu - Communications Physics, 2023‏ - nature.com
Nonequilibrium quantum states can be controlled via the driving field in periodically driven
systems. Such control, which is called Floquet engineering, has opened various …

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

P Strobel, M Daghofer - Physical Review B, 2023‏ - APS
This paper discusses Floquet engineering with arbitrary polarization in α-RuCl 3. We
describe the influence of arbitrary polarization and the limiting cases of linear and circular …
