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…

Chiral Floquet Engineering on Topological Fermions in Chiral Crystals
Benshu Fan, Wenhui Duan, Angel Rubio +1
The interplay of chiralities in light and quantum matter provides an opportunity to design and manipulate chirality-dependent properties in quantum materials. Herein we report the…
