Liquid crystals provide an ideal setting for exploring such topological phenomena through control of their characteristic defects.

WebFeb 13, 2024 · Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self.
