Probing laser-driven surface and subsurface dynamics via grazing-incidence XFEL scattering and diffraction
Lisa Randolph, Ãzgül Ãztürk, Dmitriy Ksenzov +34
We demonstrate a grazing-incidence x-ray platform that simultaneously records time-resolved grazing-incidence small-angle x-ray scattering (GISAXS) and grazing-incidence x-ray diff…
Interplay of non-local transport and local scattering during electron thermalization and spatial equilibration in laser-excited metals
Markus Uehlein, Tobias Held, Christopher Seibel +2
Ultrafast laser excitation of metals induces electronic nonequilibrium both in space and locally in the energy distribution. The subsequent dynamics are governed by the interplay b…
Electronic Signature of Melting Onset in Polycrystalline Copper at Extreme Conditions
Edna R. Toro, Tobias Held, Armin Bergermann +8
Ultrafast melting is fundamentally a structural transition of the ionic lattice, but this rearrangement also reshapes the electronic properties by changing the energy landscape and…
From Code to Figure: A FAIR-Aligned Data Provenance Chain for Reproducible Simulation Research in Numerical Physics
Markus Uehlein, Tobias Held, Christopher Seibel +3
Computational physics increasingly depends on large simulation datasets generated by software that remains under active development for many years. In such settings, reproducibilit…
Competing thermalization pathways of photoexcited hot electrons
Christopher Seibel, Tobias Held, Markus Uehlein +1
Photoexcited hot carriers in solids can drive processes, such as photocatalytic reactions on the surface, beyond those available in thermal equilibrium. Hot-electron-mediated react…
Thermalization of Optically Excited Fermi Systems: Electron-Electron Collisions in Solid Metals
Stephanie Roden, Christopher Seibel, Tobias Held +3
Ultrafast optical excitation of metals induces a non-equilibrium energy distribution in the electronic system, with a characteristic step-structure determined by Pauli blocking. On…
