Plasmonically assisted channels of photoemission from metals
Dino Novko, Vito Despoja, Marcel Reutzel +3
We analyse recently measured nonlinear photoemission spectra from Ag surfaces that reveal resonances whose energies do not scale with the applied photon energy but stay pinned to m…
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…
Electromagnetic dressing of the electron energy spectrum of Au(111) at high momenta
Marius Keunecke, Marcel Reutzel, David Schmitt +10
Light-engineering of quantum materials via electromagnetic dressing is considered an on-demand approach for tailoring electronic band dispersions and even inducing topological phas…
Towards full surface Brillouin zone mapping by coherent multi-photon photoemission
Andi Li, Namitha Ann James, Tianyi Wang +3
We report a novel approach for coherent multi-photon photoemission band mapping of the entire Brillouin zone with infrared light that is readily implemented in a laboratory setting…
Time-Resolved Momentum Microscopy with a 1 MHz High-Harmonic Extreme Ultraviolet Beamline
M. Keunecke, C. Möller, D. Schmitt +8
Recent progress in laser-based high-repetition rate extreme ultraviolet (EUV) lightsources and multidimensional photoelectron spectroscopy enable the build-up of a new generation o…
Excitation of two-photon photoemission where epsilon is near zero on Ag(111)
Marcel Reutzel, Andi Li, Branko Gumhalter +1
Because silver has epsilon-near-zero (ENZ) in the near-UV spectral region, its optical response is expected to be dominantly plasmonic and nonperturbatively nonlinear. The ENZ prop…
