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…
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.…
Skyrmion Bag Robustness in Plasmonic Bilayer and Trilayer Moiré Superlattices
Julian Schwab, Florian Mangold, Bettina Frank +2
Twistronics is studied intensively in twisted 2D heterostructures and its extension to trilayer moiré structures has proven beneficial for the tunability of unconventional correlat…
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…
Energy states of Rydberg excitons in finite crystals: From weak to strong confinement
Pavel A. Belov, Florian Morawetz, Sjard Ole Krüger +5
Due to quantum confinement, excitons in finite-sized crystals behave rather differently than in bulk materials. We investigate the dependence of energies of Rydberg excitons on the…
Nanoantenna-enhanced ultrafast nonlinear spectroscopy of a single gold nanoparticle
Thorsten Schumacher, Kai Kratzer, David Molnar +3
Optical nanoantennas are a novel tool to investigate previously unattainable dimensions in the nanocosmos. Just like their radio-frequency equivalents, nanoantennas enhance the lig…
