On the limits of the energetic coupling between field dislocation mechanics and phase field crystal
Aymane Graini, Jorge Viñals, Manas V. Upadhyay
This paper investigates the energetic coupling between Field Dislocation Mechanics (FDM) and the Phase Field Crystal (PFC) model proposed in Phys. Rev. B 102, 064109, 2020. While F…
Self-consistent field theory of semiflexible nematics: Density-nematic coupling, anisotropic elasticity, and defect core sizes
Longyu Qing, Jorge Viñals
The linear response of wormlike chains in the nematic phase is studied by self-consistent field theory. The model Hamiltonian incorporates Maier--Saupe orientational interactions t…
Biomechanics of orientationally ordered epithelial tissue
Patrick W. Alford, Luiza Angheluta, Jorge Vinals
Organogenesis involves large deformations and complex shape changes that require elaborate mechanical regulation. Models of tissue biomechanics have been introduced to account for…
A computational study of nematic core structure and disclination interactions in elastically anisotropic nematics
Lucas Myers, Carter Swift, Jonas Ronning +2
A singular potential method in the Q tensor order parameter representation of a nematic liquid crystal is used to study the equilibrium configuration of a disclination dipole. Unli…
Self Consistent Field Theory of isotropic-nematic interfaces and disclinations in a semiflexible molecule nematic
Longyu Qing, Jorge Viñals
A Self Consistent Field Theory description of equilibrium, but non uniform, configurations adopted by semi flexible liquid crystal molecules is presented. Two cases are considered,…
Chiral ground states in a nematic liquid crystal confined to a cylinder with homeotropic anchoring
Lucas Myers, Jorge Viñals
The singular potential method in the Q tensor order parameter representation is used to determine the ground state configuration of an elastically anisotropic nematic liquid crysta…
