Division of drops of a liquid crystal in the case of a cholesteric-smectic-A phase transition
Lavrentovich O. D. , Nastishin Yu. A.
The spontaneous division of liquid-crystal drops, suspended freely in an isotropic matrix has been detected following a cholesteric-smectic-^ phase transition, caused by an anomalous increase of the surface area of the drops in the pretransitional region. It is suggested that the surface energy of the cholesteric-smectic-Λ interface can be negative.
