Chiral crystals
WebMar 30, 2024 · Chiral crystals come in two mirror-symmetric forms, and Sakano et al. found that the handedness of the crystal determines whether the radial spins point inward or outward. The range of spin textures that a crystal can adopt is constrained by the crystal’s symmetries and the way that each symmetry affects spin. WebJun 14, 2024 · Hands, like the crystals Pasteur would eventually discover, are chiral. And that discovery all came down to an accident in a vat of wine. Molecular secrets in wine
