Ultrafast Electrons in Noble Metals: Orientational Relaxation, Thermalization and Cooling in Terms of Electron-Phonon Interaction
Jonas Grumm, Andreas Knorr
We investigate the momentum-resolved dynamics of conduction electrons in noble metals following ultrashort optical excitation with linearly polarized light. Using a momentum-resolv…

Theory of Non-Linear Electron Relaxation in Thin Gold Films and Their Signatures in Optical Observables
Jonas Grumm, Malte Selig, Holger Lange +1
Based on the momentum-resolved Boltzmann equation, we provide self-consistent numerical calculations of the dynamics of conduction electrons in thin noble metal films after linear…

Ab initio Maxwell-Bloch Approach for X-Ray Excitations in Two-Dimensional Materials
Joris Sturm, Ivan Maliyov, Dominik Christiansen +3
The combination of Maxwell and X-ray Bloch equations forms an appropriate framework to describe ultrafast time-resolved X-ray experiments on attosecond time scale in crystalline so…
