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…
Dynamic Breaking of Mirror Symmetry in Spin-Dependent Electron Transport through Chiral Media Causes Enantiomeric Excesses
Yossi Paltiel, Daniel Goldberg, Nir Yuran +9
Two fundamental questions have puzzled scientists for more than 150 years. How did life become homochiral and why was this specific handedness selected. Recently, it has been shown…
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…
Dynamic interfacial effects in ultrathin ferromagnetic bilayers
Anulekha De, Christopher Seibel, Sanjay Ashok +7
We investigate the magnetization dynamics of an ultrathin Co (1.5 nm) /Py (1.5 nm) bilayer system from femtosecond (fs) to nanosecond (ns) timescales. Magnetization dynamics in the…
