First-principles Floquet analysis from real-time propagation
Ruipeng Li, Benshu Fan, Umberto De Giovannini +2
We present a real-time Floquet analysis method for extracting quasi-energies and Floquet states directly from propagated wavefunctions. By reconstructing the one-period evolution o…

Floquet optical selection rules in black phosphorus
Benshu Fan, Umberto De Giovannini, Hannes Hübener +4
Optical selection rules endorsed by symmetry are crucial for understanding the optical properties of quantum materials and the associated ultrafast spectral phenomena. Here, we int…
