  • Title: Field-induced switching between states of opposite chirality in a liquid-crystalline phase.
    Author: Eremin A, Diele S, Pelzl G, Weissflog W.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2003 Feb; 67(2 Pt 1):020702. PubMed ID: 12636646.
    Abstract:
    A tilted smectic phase of a new achiral banana-shaped mesogen is presented. It possesses liquidlike order within the layers and appears with a fan-shaped texture. At sufficiently high electric fields, this texture can be transformed into a texture that displays a complete extinction between crossed polarizers and it forms randomly distributed chiral domains. Above a threshold these domains can be reversibly switched into a state of opposite handedness.
