Analysis of the Topology of a Plasmonic Target-Skyrmion Texture
Alexander Neuhaus, Pascal Dreher, Philipp Gessler +5
Topological concepts are frequently used to describe structured optical fields, including plasmonic near fields. Topological descriptions in terms of skyrmion numbers implicitly as…
Linking extended vector wave fields with momentum space topology
A. Neuhaus, P. Gessler, P. Dreher +10
Topology describes properties of physical systems that remain constant under continuous deformations. For infinite vector waves, global topological invariants in position space are…
Spatio-temporal topology of plasmonic spin meron pairs revealed by polarimetric photo-emission microscopy
Pascal Dreher, Alexander Neuhaus, David Janoschka +6
Topology is the study of geometrical properties and spatial relations unaffected by continuous changes, and has become an important tool for understanding complex physical systems.…
Plasmonic Twistronics: Discovery of Plasmonic Skyrmion Bags
Julian Schwab, Alexander Neuhaus, Pascal Dreher +9
The study of van der Waals heterostructures with an interlayer twist, known as "twistronics", has been instrumental in advancing contemporary condensed matter research. Most import…
Momentum space separation of quantum path interferences between photons and surface plasmon polaritons in nonlinear photoemission microscopy
Pascal Dreher, David Janoschka, Harald Giessen +4
Quantum path interferences occur whenever multiple equivalent and coherent transitions result in a common final state. Such interferences strongly modify the probability of a parti…
Angle-resolved photoelectron spectroscopy in a low energy electron microscope
Alexander Neuhaus, Pascal Dreher, Florian Schütz +3
Spectroscopic photoemission microscopy is a well-established method to investigate the electronic structure of surfaces. In modern photoemission microscopes the electron optics all…
