Near-Perfect Chirality and Giant Spin-Orbit Conversion in a Single Plasmonic Cavity
arXiv:2606.04393v1 Announce Type: new Abstract: To overcome the difficulty of single nanostructures in approaching the theoretical limit of chiroptical performance, we design a single plasmonic twisted dimer cavity whose magnetic gap plasmon mode enables magnetic polarization near-field engineering for high chirality. The structure exhibits strong extinction under circularly polarized excitation with one handedness, while its response to the orthogonally circularly polarized light is almost...
