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…
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…
Circular dichroism in the photoelectron angular distribution of achiral molecules
Christian S. Kern, Xiaosheng Yang, Giovanni Zamborlini +9
Circular dichroism in the angular distribution (CDAD) is the effect that the angular intensity distribution of photoemitted electrons depends on the handedness of the incident circ…
Symmetry-Driven Floquet Engineering in Multivalley SnS
Sotirios Fragkos, Benshu Fan, Umberto De Giovannini +5
Coherent interactions between time-periodic electromagnetic fields and materials offer a powerful platform for engineering light-matter hybrid Floquet states with tailored function…
Polarized Houston State Framework for Nonequilibrium Driven Open Quantum Systems
Shunsuke A. Sato, Hannes Hübener, Umberto De Giovannini +1
We introduce a new theoretical framework -- the polarized Houston basis -- to model nonequilibrium dynamics in driven open quantum systems, formulated for use within the quantum ma…
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…
