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 …

We give a description of the intrinsic geometry of elastic distortions in three-dimensional
nematic liquid crystals and establish necessary and sufficient conditions for a set of functions …

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 …

The elastic theory of chromonic liquid crystals is not completely established. We know, for
example, that for anomalously low twist constants (needed for chromonics) the classical …

Tactoids are pointed, spindlelike droplets of nematic liquid crystal in an isotropic fluid. They
have long been observed in inorganic and organic nematics, in thermotropic phases as well …

In its most restrictive definition, an octupolar tensor is a fully symmetric traceless third-rank
tensor in three space dimensions. So great a body of works have been devoted to this …

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 …
