Optimized Effective Potential for Quantum Electrodynamical Time-Dependent Density Functional Theory
Camilla Pellegrini, Johannes Flick, Ilya V. Tokatly +2
We propose a practical approximation to the exchange-correlation functional of (time-dependent) density functional theory for many-electron systems coupled to photons. The (time no…
Quantum Electrodynamical Density-Functional Theory: Bridging Quantum Optics and Electronic-Structure Theory
Michael Ruggenthaler, Johannes Flick, Camilla Pellegrini +3
In this work we give a comprehensive derivation of an exact and numerically feasible method to perform ab-initio calculations of quantum particles interacting with a quantized elec…
Non-adiabatic and time-resolved photoelectron spectroscopy for molecular systems
Johannes Flick, Heiko Appel, Angel Rubio
We quantify the non-adiabatic contributions to the vibronic sidebands of equilibrium and explicitly time-resolved non-equilibrium photoelectron spectra for a vibronic model system…
