Enhanced multiphoton ionization driven by quantum light
Valeriia P. Kosheleva, Shahram Panahiyan, Angel Rubio +1
We present a framework for multiphoton ionization driven by arbitrary quantum states of light. Our simulations predict that cross sections can be enhanced by more than two orders o…

Linear-Response Quantum-Electrodynamical Density Functional Theory Based on Two-Component X2C Hamiltonians
Lukas Konecny, Valeriia P. Kosheleva, Michael Ruggenthaler +2
Linear-response quantum electrodynamical density functional theory (QEDFT) enables the description of molecular spectra under strong coupling to quantized photonic modes, such as t…

High Harmonic Generation with Orbital Angular Momentum Beams: Beyond-dipole Corrections
Esra Ilke Albar, Valeriia P. Kosheleva, Heiko Appel +2
We study the high harmonic generation with vortex beams beyond the dipole approximation. To do so we employ the full minimal coupling approach to account for multipolar coupling wi…
