We demonstrate that plasmonic near fields can selectively enhance optical chirality or spin angular momentum—two quantities typically inseparable in circularly polarized light—thus enabling their roles in light–matter interactions to be disentangled.

3–O24, SP7 (5025) 11:00 "Photoelectrochemical Chiral Nanofabrication by Circularly Polarized Light" T. Ishida, T. Tatsuma (Utsunomiya Univ.; The Univ. of Tokyo)
Researchers report the first direct observation of chiral magnons exhibiting right‑ and left‑handed chirality in an altermagnet. They also demonstrated that this chirality can be reversibly switched by an external magnetic field, opening up possibilities for low‑dissipation, high‑density spintronic devices.
