Bulk and surface biaxiality in nematic liquid crystals
Paolo Biscari, Gaetano Napoli, Stefano Turzi
Nematic liquid crystals possess three different phases: isotropic, uniaxial, and biaxial. The ground state of most nematics is either isotropic or uniaxial, depending on the extern…
Boundary-roughness effects in nematic liquid crystals
Paolo Biscari, Stefano Turzi
We study the equilibrium configuration of a nematic liquid crystal bounded by a rough surface. The wrinkling of the surface induces a partial melting in the degree of orientation.…
Field-induced motion of nematic disclinations
Paolo Biscari, Timothy J. Sluckin
An individual defect in a nematic liquid crystal moves not only in response to its interaction with other defects but also in response to an external field. We analyze the motion o…
Telephone-cord instabilities in thin smectic capillaries
Paolo Biscari, Maria Carme Calderer
Telephone-cord patterns have been recently observed in smectic liquid crystal capillaries. In this paper we analyse the effects that may induce them. As long as the capillary keeps…
Impermeability effects in three-dimensional vesicles
Paolo Biscari, Silvia Maria Canevese, Gaetano Napoli
We analyse the effects that the impermeability constraint induces on the equilibrium shapes of a three-dimensional vesicle hosting a rigid inclusion. A given alteration of the incl…
