WebApr 26, 2024 · We show that chiral symmetry breaking may occur spontaneously and generically by harnessing energy sources from external environmental drives. A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. In chemistry, … See more Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object. An object or a … See more In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins.
