Chromonic liquid crystals are lyotropic materials which are attracting growing interest for
their adaptability to living systems. To describe their elastic properties, the classical Oseen …

Chromonic liquid crystals constitute a novel lyotropic phase, whose elastic properties have
so far been modeled within the classical Oseen-Frank theory, provided that the twist …

The ground state of chromonic liquid crystals, as revealed by a number of recent
experiments, is quite different from that of ordinary nematic liquid crystals: it is twisted …

An elastic quartic twist theory has recently been proposed for chromonic liquid crystals,
intended to overcome the paradoxical conclusions encountered by the classical Oseen …

Twisted hedgehogs are defects in spherical cavities with homeotropic anchoring for the
nematic director that arise when twist distortions are sufficiently less energetic than splay …

Chromonic nematics are lyotropic liquid crystals that have already been known for half a
century, but have only recently raised interest for their potential applications in life sciences …

Chromonic nematics are lyotropic liquid crystals that have already been known for half a

Toroidal nematics are nematic liquid crystals confined within a circular torus and subject to
planar degenerate anchoring on the boundary of the torus. They may be droplets floating in …

ABSTRACT Based on Landau-de Gennes theory and differential iteration method, in a
cylindrical shell with degenerate planar anchoring at both interfaces, the double-twist …

Abstract Based on Landau-de Gennes theory, electric field-induced structure transition of
negative nematic liquid crystals in submicron-confined cylinder cells was investigated. The …
