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…
Intrinsic plasmon canalization in the biaxial van der Waals crystal MoOCl
Farid Aghashirinov, Andrea Mancini, Lin Nan +4
Anisotropic polaritons in low-symmetry crystals allow for subwavelength confinement and directional routing of light. The most extreme form of such anisotropy arises at the topolog…
Phonon-polaritonic skyrmions: Transition from bubble- to Néel-type
Florian Mangold, Enrico Baù, Lin Nan +6
Optical skyrmions are members of the emerging topological branch of solid-state physics and photonics, allowing for control over topological light textures through light-matter int…
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…
Phyllotaxis-inspired Nanosieves with Multiplexed Orbital Angular Momentum
Zhongwei Jin, David Janoschka, Junhong Deng +15
Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex ge…
Femtosecond field-driven on-chip unidirectional electronic currents in nonadiabatic tunnelling regime
Liping Shi, Ihar Babushkin, Anton Husakou +10
Recently, asymmetric plasmonic nanojunctions [Karnetzky et. al., Nature Comm. 2471, 9 (2018)] have shown promise as on-chip electronic devices to convert femtosecond optical pulses…
Highly Confined In-plane Exciton-Polaritons in Monolayer Semiconductors
Itai Epstein, Andre J. Chaves, Daniel A. Rhodes +7
2D materials support unique excitations of quasi-particles that consist of a material excitation and photons called polaritons. Especially interesting are in-plane propagating pola…
Near-unity light absorption in a monolayer WS2 van der Waals heterostructure cavity
Itai Epstein, Bernat Terrés, André J. Chaves +12
Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical response and exhibit strong light-matter interactions with lifetime-limited emission. While var…
