Laser-induced metastable (anti-)skyrmion states with higher-order topological charge
Tim Titze, Marcel Möller, Timo Schmidt +6
Ultrafast creation and manipulation of topologically non-trivial spin objects promises significant potential for spintronic applications. Here, we demonstrate laser-induced nucleat…
Ultrafast order-selective electron imaging and spectroscopy
Jan Philipp Bange, Till Domröse, Claus Ropers +3
Ultrafast pump-probe spectroscopies in energy and momentum have become indispensable for probing non-equilibrium dynamics in quantum materials, revealing pathways in ultrafast ener…
Surface-Sensitive Mapping of Anisotropic Phonon Cascades in T-WTe
Alp Akbiyik, Felix Kurtz, Nandana Veena Uday +3
Understanding how energy flows from photoexcited carriers into the lattice is essential for describing nonequilibrium phenomena in low-symmetry quantum materials. Here, we use ultr…
Evidence for reduced periodic lattice distortion within the Sb-terminated surface layer of the kagome metal CsVSb
Felix Kurtz, Gevin von Witte, Lukas Jehn +8
The discovery of the kagome metal CsVSb sparked broad interest, due to the coexistence of a charge density wave (CDW) phase and possible unconventional superconductivity in…
Optical switching of ferro-rotational charge-density wave states
Wayne Cheng-Wei Huang, Sai Mu, Gevin von Witte +7
Tailored optical excitations can steer a system along non-equilibrium pathways to metastable states with specific structural or electronic properties. The light-induced hidden stat…
Valley-controlled photoswitching of metal-insulator nanotextures
Hannes Böckmann, Jan Gerrit Horstmann, Felix Kurtz +5
Spatial heterogeneity and phase competition are hallmarks of strongly-correlated materials, promising tunable functionality on the nanoscale. Light-induced switching of a correlate…
Quantum effects in the interaction of low-energy electrons with light
Adamantios P. Synanidis, P. A. D. Gonçalves, Claus Ropers +1
The interaction between free electrons and nanoscale optical fields has emerged as a unique platform to investigate ultrafast processes in matter and explore fundamental quantum ph…
