Selective Enhancement of Optical Chirality and Spin Angular Momentum in Plasmonic Near-Field
Naoki Ichiji, Takuya Ishida, Ikki Morichika +3
The interaction between circularly polarized (CP) light and matter is governed by two fundamental quantities: spin angular momentum (SAM) and optical chirality (OC). While these qu…

Designing rotational motion of charges on plasmonic nanostructures excited by circularly polarized light
Naoki Ichiji, Takuya Ishida, Ikki Morichika +3
Rotational motion of charges in plasmonic nanostructures plays an important role in transferring angular momentum between light and matter on the nanometer scale. Although sophisti…

Rotationally displaced electric field intensity distribution around square nanoantennas induced by circularly polarized light
Naoki Ichiji, Takuya Ishida, Ikki Morichika +2
An optical field around regular polygon metal nanostructures excited by circularly polarized light can exhibit rotationally displaced intensity distributions. Although this phenome…
