Optical signatures of bulk g-wave altermagnetism in MnTe
Luca Haag, Marius Weber, Kai Leckron +3
For planar d-wave altermagnets, it has been shown that a spin polarization can be induced in a controlled fashion by ultrashort-pulse excitation, even though the material is magnet…
Ultrafast electron dynamics in altermagnetic materials
Marius Weber, Kai Leckron, Luca Haag +4
Altermagnets constitute a new class of magnetic materials that combine properties previously thought to be exclusive to either antiferromagnets or ferromagnets, and have unique pro…
All optical excitation of spin polarization in d-wave altermagnets
Marius Weber, Stephan Wust, Luca Haag +14
The recently discovered altermagnets exhibit collinear magnetic order with zero net magnetization but with unconventional spin-polarized d/g/i-wave band structures, expanding the k…
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…
Competing signatures of intersite and interlayer spin transfer in the ultrafast magnetization dynamics
Simon Häuser, Sebastian T. Weber, Christopher Seibel +10
Optically driven intersite and interlayer spin transfer are individually known as the fastest processes for manipulating the spin order of magnetic materials on the sub 100 fs time…
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…
Direct Access to Auger recombination in Graphene
Marius Keunecke, David Schmitt, Marcel Reutzel +15
Auger scattering channels are of fundamental importance to describe and understand the non-equilibrium charge carrier dynamics in graphene. While impact excitation increases the nu…
Excitation of higher-order modes in optofluidic photonic crystal fiber
Andrei Ruskuc, Philipp Koehler, Marius A. Weber +4
Higher-order modes up to LP are controllably excited in water-filled kagomé- and bandgap-style hollow-core photonic crystal fibers (HC-PCF). A spatial light modulator is use…
