Influence of band occupation on electron-phonon coupling in gold
Tobias Held, Sebastian T. Weber, Baerbel Rethfeld
Electron-phonon coupling is a fundamental process that governs the energy relaxation dynamics of solids excited by ultrafast laser pulses. It has been found to strongly depend on e…
Time-resolved spectral densities of non-thermal electrons in gold
Christopher Seibel, Markus Uehlein, Tobias Held +3
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…
Ultrafast electron-phonon scattering in antiferromagnetic Dirac semimetals
Marius Weber, Kai Leckron, Libor Šmejkal +3
Topological antiferromagnetic systems, which exhibit anisotropic band structures combined with complex relativistic spin structures in momentum space, have shown strong magnetoresi…
Intertwined relaxation processes maintain athermal electron distribution in laser-excited dielectrics
Nils Brouwer, Steffen Hirtle, Baerbel Rethfeld
We study the relaxation dynamics of laser-excited non-equilibrium electron distributions in the valence- and conduction band of a dielectric. We apply Boltzmann collision integrals…
Interplay of electron-magnon scattering and spin-orbit induced electronic spin-flip scattering in a two-band Stoner model
Félix Dusabirane, Kai Leckron, Baerbel Rethfeld +1
This paper presents a theoretical investigation of electron-magnon scattering processes in the ultrafast demagnetization in itinerant ferromagnets. In the framework of a ferromagne…
Effect of iron thicknesses on spin transport in a Fe/Au bilayer system
J. Briones, M. Weber, B. Stadtmüller +2
This paper is concerned with a theoretical analysis of the behavior of optically excited spin currents in bilayer and multilayer systems of ferromagnetic and normal metals. As the…
