Researchers at Rice University have discovered details about a novel type of polarized light-matter interaction, with light that literally turns end over end as it propagates from a source. This discovery could help study molecules like those in light-harvesting antennas anticipated to have unique sensitivity to the phenomenon. The researchers observed the effect in the light scattered by a pair of closely spaced plasmonic metal nanorods, when they were excited by the cartwheeling light.
