Optical conductivity of a topological system driven using a realistic pulse
R Seshadri, T Pereg-Barnea - Physical Review B, 2023 - APS
The effect of a time-periodic perturbation, such as radiation, on a system otherwise at
equilibrium has been studied in the context of Floquet theory with stationary states replaced …

Emergent Weyl-like points in periodically modulated systems and Floquet engineering
We investigate a three-dimensional topological phase resembling a Weyl semimetal,
modulated by a periodic potential and engineered through Floquet dynamics. This system is …
