First-principles electron-phonon scattering in real-time TDDFT
Zhengwei Nie, Subhojit Pal, Marti Lüders +4
Real-time time-dependent density functional theory provides a first-principles description of coherent electron dynamics in laser-driven solids, but its unitary formulation cannot…
Trapping in a Casimir Force Set-Up Controlled by Solution Permeability
S. Pal, L. Inacio, L. M. Woods +3
We have designed a system enabling tuning Casimir attraction/repulsion transitions between a polystyrene sphere attached to an atomic force microscope tip near a Teflon surface in…
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…
Light-induced renormalization of the band structure of chiral tellurium
G. Gatti, N. Tancogne-Dejean, H. Hübener +11
Chirality in tellurium derives from a Peierls distortion driven by strong electron-phonon coupling, making this material a unique candidate for observing a light-induced topologica…
A time-based Chern number in periodically-driven systems in the adiabatic limit
I-Te Lu, Dongbin Shin, Umberto De Giovannini +4
To define the topology of driven systems, recent works have proposed synthetic dimensions as a way to uncover the underlying parameter space of topological invariants. Using time a…
Terahertz driven extremely nonlinear bulk photogalvanic currents in non-resonant conditions
Ofer Neufeld, Nicolas Tancogne-Dejean, Umberto De Giovannini +2
We report on the generation of bulk photocurrents in materials driven by non-resonant bi-chromatic fields that are circularly polarized and co-rotating. The nonlinear photocurrents…
