Multiple ordering transitions in a chiral liquid

We present here a numerical study of a lattice model of a chiral liquid. The low symmetry of the favoured local structure depresses the freezing point to reveal an exotic liquid-liquid transition characterised by the appearance of an extended chirality,prior to freezing. What mechanisms impede crystallisation in liquids with low molecular symmetry ? The ordered liquid can be readily supercooled to zero temperature, as the combination of critical slowing down and competing crystal polymorphs results in a dramatically slow crystallisation process.
