Structured Optical Fields Reveal Nanoscale Chiral Light-Matter Interactions Governed by Optical Chirality
Atsushi Kamegaya, Shun Hashiyada, Yoshito Y. Tanaka
Optical chirality has been proposed as the local electromagnetic quantity governing chiral light-matter interactions, yet in conventional circularly polarized fields its magnitude…

Real-Space Double Crossing Reveals Symmetry-Driven Dispersion Back-Bending of Surface Phonon Polaritons on α-Quartz
Ryoga Odawara, Kotaro Shirahata, Aozora Ohi +2
Surface phonon polaritons (SPhPs) in anisotropic crystals exhibit direction-dependent propagation and dispersion, yet how their dispersion back-bending manifests in real space has…
