WebMay 19, 2024 · A molecule’s chirality can determine whether it is medicinal or toxic, and the breaking of chiral symmetry is responsible for the mass of the proton in the matter inside and around us (see Focus: Nobel … WebElaborate statements are even made to the effect that charge conjugation changes chirality. This makes no sense whatsoever, and can be best seen with Weyl fields for which chirality is the same as helicity. Helicity involves spin and momentum, none of which changes under charge conjugation. Thus helicity is unaffected by charge conjugation, …
WebJul 20, 2016 · chiral: [adjective] of or relating to a molecule that is not superimposable on its mirror image. WebThe most popular explanation for the existence of chiral edge states is probably the following: in a magnetic field, electrons move in cyclotron orbits, and such such cyclotron orbits ensure electrons to move in a single direction at the edge. That is why the edge state is chiral. I think this picture is too classical.
