WebNeutrinos can be left-chiral or right-chiral. Physicists have seen only neutrinos born in a left-chiral state, and only right-chiral antineutrinos. So chirality is built in, but helicity is a matter of perspective. Something that could overtake a neutrino—say, a speedy photon—would see the neutrino’s helicity flip. WebWe design, in a most simple way, Fabry–Perot cavities with longitudinal chiral modes by sandwiching between two smooth metallic silver mirrors a layer of polystyrene made planar chiral by torsional shear stress. We demonstrate that the helicity-preserving features of our cavities stem from a spin–orbit coupling mechanism seeded inside the cavities by the … nourish organic body lotion in almond vanilla https://designchristelle.com
