Nematic Bubbles and the Breaking of Spherical Symmetry
Gaetano Napoli, Silvia Paparini
The emergence of nematic order on deformable closed surfaces plays a pivotal role in the morphogenesis of active biological matter, such as the regeneration of Hydra. In this work,…
A Review on Phenomenological Models for Chromonic Liquid Crystals
Silvia Paparini
Chromonic liquid crystals (CLCs) are lyotropic materials which are attracting growing interest for their adaptability to living systems. A considerable body of works has been devot…
Singular Twist Waves in Chromonic Liquid Crystals
Silvia Paparini, Epifanio G. Virga
Chromonic liquid crystals are lyotropic nematic phases whose applications span from food to drug industries. It has recently been suggested that the elastic energy density governin…
Inversion Ring in Chromonic Twisted Hedgehogs: Theory and Experiment
Federica Ciuchi, Maria Penelope De Santo, Silvia Paparini +2
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…
What a twist cell experiment tells about a quartic twist theory for chromonics
Silvia Paparini, Epifanio G. Virga
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…
A geometric method to determine chromonics' planar anchoring strength
Silvia Paparini, Epifanio G. Virga
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 sc…
An Elastic Quartic Twist Theory for Chromonic Liquid Crystals
Silvia Paparini, Epifanio G. Virga
Chromonic liquid crystals are lyotropic materials which are attracting growing interest for their adapatbility to living systems. To describe their elastic properties, the classica…
Paradoxes for Chromonic Liquid Crystal Droplets
Silvia Paparini, Epifanio G. Virga
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 con…
Stability Against the Odds: the Case of Chromonic Liquid Crystals
Silvia Paparini, Epifanio G. Virga
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 instea…
Shape Bistability in Squeezed Chromonic Droplets
Silvia Paparini, Epifanio G. Virga
We study droplets of chromonic liquid crystals squeezed between parallel plates inducing degenerate tangential anchoring on the nematic director. In the coexistence regime, where d…
Nematic Tactoid Population
Silvia Paparini, Epifanio G. Virga
Tactoids are pointed, spindle-like droplets of nematic liquid crystal in an isotropic fluid. They have long been observed in inorganic and organic nematics, in thermotropic phases…
