Robust purely optical signatures of Floquet states in laser-dressed crystals
Vishal Tiwari, Roman Korol, Ignacio Franco
Strong light-matter interactions can create non-equilibrium materials with on-demand novel functionalities. For periodically driven solids, the Floquet theorem provides the natural…

First-principle based Floquet engineering of solids in the velocity gauge
Vishal Tiwari, Ignacio Franco
We introduce a practical and accurate strategy to capture light-matter interactions using the Floquet formalism in the velocity gauge in combination with realistic first-principle…
