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…
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…
Control of transport phenomena in magnetic heterostructures by wavelength modulation
Christopher Seibel, Marius Weber, Martin Stiehl +5
We demonstrate the tuneablity of the ultrafast energy flow in magnetic/non-magnetic bilayer structures by changing the wavelength of the optical excitation. This is achieved by an…
Energy and Momentum Distribution of Surface Plasmon-induced Hot Carriers Isolated via Spatiotemporal Separation
Michael Hartelt, Pavel N. Terekhin, Tobias Eul +6
Understanding the differences between photon-induced and plasmon-induced hot electrons is essential for the construction of devices for plasmonic energy conversion. The mechanism o…
Phonon-induced long-lasting nonequilibrium in the electron system of a laser-excited solid
Sebastian T. Weber, Baerbel Rethfeld
Electron-electron thermalization and electron-phonon relaxation processes in laser-excited solids are often assumed to occur on different timescales. This is true for the majority…
Femtosecond formation dynamics of the spin Seebeck effect revealed by terahertz spectroscopy
T. S. Seifert, S. Jaiswal, J. Barker +18
Understanding the transfer of spin angular momentum is essential in modern magnetism research. A model case is the generation of magnons in magnetic insulators by heating an adjace…
Laser damage in silicon: energy absorption, relaxation and transport
A. Rämer, O. Osmani, B. Rethfeld
Silicon irradiated with an ultrashort 800 nm-laser pulse is studied theoretically using a two temperature description that considers the transient free carrier density during and a…
