Quantum electrodynamics in high harmonic generation: multi-trajectory Ehrenfest and exact quantum analysis
Sebastián de-la-Peña, Ofer Neufeld, Matan Even Tzur +3
High-harmonic generation (HHG) is a nonlinear process in which a material sample is irradiated by intense laser pulses, causing the emission of high harmonics of the incident light…

Full minimal coupling Maxwell-TDDFT: an ab initio framework for light-matter phenomena beyond the dipole approximation
Franco P. Bonafé, Esra Ilke Albar, Sebastian T. Ohlmann +5
We report the first ab initio, non-relativistic QED method that couples light and matter self-consistently beyond the electric dipole approximation and without multipolar truncatio…

Relativistic Linear Response in Quantum-Electrodynamical Density Functional Theory
Lukas Konecny, Valeriia P. Kosheleva, Heiko Appel +2
We present the theoretical derivation and numerical implementation of the linear response equations for relativistic quantum electrodynamical density functional theory (QEDFT). In…
