WebApr 3, 2024 · For left-handed chiral crystals, the orbital angular momentum generated by chirality is a left-handed spiral, which is the opposite of the right-handed chiral crystals . As a result, the left-handed chiral crystals could enhance the hopping of the right-handed component (σ+) to let more left-handed components (σ−) go through the crystals ... WebChiral model. In nuclear physics, the chiral model, introduced by Feza Gürsey in 1960, is a phenomenological model describing effective interactions of mesons in the chiral limit …
