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…
Ridge approximation for thin nematic polymer networks
Andrea Pedrini, Epifanio G. Virga
Nematic polymer networks (NPNs) are nematic elastomers within which the nematic director is enslaved to the elastic deformation. The elastic free energy of a NPN sheet of thickness…
Leaky Cell Model of Hard Spheres
Thomas G. Fai, Jamie M. Taylor, Epifanio G. Virga +2
We study packings of hard spheres on lattices. The partition function, and therefore the pressure, may be written solely in terms of the accessible free volume, i.e. the volume of…
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…
Ridge energy for thin nematic polymer networks
Andrea Pedrini, Epifanio G. Virga
Minimizing the elastic free energy of a thin sheet of nematic polymer network among smooth isometric immersions is the strategy purported by the mainstream theory. In this paper, w…
