Collapse of electron–phonon coupling due to nonthermal phonon populations Open
Electron–phonon coupling governs the energy transfer rate between electrons and the crystal lattice. It is of crucial importance to the relaxation dynamics of laser-excited solids, as only the electron system can be directly excited by opt…

Intrinsically energy-dependent spin dynamics in ultrafast demagnetization Open
Ultrafast magnetization dynamics has the potential to spark a new era of information technology by harnessing the interaction between spin and light. Recent studies indicate a complex interplay between the microscopic spin and band structu…

Capturing non-equilibrium electron dynamics in metals accurately and efficiently Open
The simulation of non-equilibrium electron distributions is essential for capturing light–metal interactions and therefore the study of photoabsorption, photocatalysis, laser ablation, and many other phenomena. Current methodologies, such …

Time-resolved spectral densities of non-thermal electrons in gold Open
Noble-metal nanoparticles for photocatalysis have become a major research object in recent years due to their plasmon-enhanced strong light-matter interaction. The dynamics of the hot electrons in the noble metal are crucial for the effici…

Influence of Electronic Non-Equilibrium on Energy Distribution and Dissipation in Aluminum Studied with an Extended Two-Temperature Model Open
When an ultrashort laser pulse excites a metal surface, only a few of all the free electrons absorb a photon. The resulting non-equilibrium electron energy distribution thermalizes quickly to a hot Fermi distribution. The further energy di…

Implementation of the electronic non-equilibrium in the two-temperature model Open
We investigate a temperature-based model, called extended two-temperature model (eTTM), that describes the electronic non-equilibrium and its effect on energy dissipation in metals after ultrashort laser excitation. We derive and discuss i…
