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. But since humans don ... Web1 day ago · A team of researchers led by Nicholas Kotov has now shown that nanostructures with an anisotropic bowtie shape have continuous chirality, meaning that that they can be fabricated with a twist angle, pitch width, thickness and length that can be tuned over a wide range. Indeed, the twist can be controlled all the way from a fully …
