A chiral inverse Faraday effect mediated by an inversely designed plasmonic antenna
Nanophotonics, 2023 The inverse Faraday effect is a magneto-optical process allowing the magnetization of matter by an optical excitation carrying a non-zero spin of light. This phenomenon was considered until now as symmetric; right or left circular polarizations generate ...
