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…
Unveiling orbital optical chirality through multipolar chiral light-matter interaction
Shun Hashiyada, An'an Wu, Yoshito Y. Tanaka
Chiral light-matter interactions have traditionally been understood in terms of electric-magnetic dipolar interference driven by light with spin angular momentum. Here, we show tha…
3-dimensional plasmonic nanomotors enabled by independent integration of Optical Pulling and Lateral Forces
Guillermo Serrera, Yoshito Y. Tanaka, Pablo Albella
Light-matter interactions generally involve momentum exchange between incident photons and the target object giving rise to optical forces and torques. While typically weak, they b…
Conservation law for angular momentum based on optical field derivatives: Analysis of optical spin-orbit conversion
Shun Hashiyada, Yoshito Y. Tanaka
We present a theoretical framework for analyzing the loss of optical angular momentum (AM), including spin (SAM) and orbital (OAM) components, in light-matter interactions. Convent…
