The existence of the parity-breaking phase transition between untwisted and twisted bipolar structures of the tangentially anchored spherical nematic drops has been shown experimentally. Twisted structures behave like the optically active objects in

The existence of polar electro-optic effect induced by a surface polarization of a nematic liquid crystal is proved using a simultaneous action of vertical dc and high-frequency ac electric fields on the homeotropically aligned nematic liquid crystal

The rearrangements in dispersed nematic drops with normal boundary conditions in an external ac electric field have been closely investigated with a polarizing microscope. It is shown both experimentally and theoretically that the dependence of the c
