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…
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…
Effective Equilibrium Theory of Quantum Light-Matter Interaction in Cavities: Extended Systems and the Long Wavelength Approximation
Mark Kamper Svendsen, Michael Ruggenthaler, Hannes Hübener +4
When light and matter interact strongly, the resulting hybrid system inherits properties from both constituents, allowing one to modify material behavior by engineering the surroun…
Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption
Wenqing Li, Xiaosong Zhu, Pengfei Lan +5
We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorptio…
