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.…
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…
