Mathematical problems of nematic liquid crystals: between dynamical and stationary problems

A Zarnescu - … Transactions of the Royal Society A, 2021 - royalsocietypublishing.org
Mathematical studies of nematic liquid crystals address in general two rather different
perspectives: that of fluid mechanics and that of calculus of variations. The former focuses on …

Tailored nematic and magnetization profiles on two-dimensional polygons

Y Han, J Harris, J Walton, A Majumdar - Physical Review E, 2021 - APS
We study dilute suspensions of magnetic nanoparticles in a nematic host, on two-
dimensional polygons. These systems are described by a nematic order parameter and a …

Homogenization modelling of antibiotic diffusion and adsorption in viral liquid crystals

MT van Rossem, S Wilks, PR Secor… - Royal Society …, 2023 - royalsocietypublishing.org
Systems of rod-shaped viruses have long been important to the science of living liquid
crystals, as their monodispersity and uniform charge make them convenient model systems …

Far-field expansions for harmonic maps and the electrostatics analogy in nematic suspensions

S Alama, L Bronsard, X Lamy… - Journal of Nonlinear …, 2023 - Springer
For a smooth bounded domain G⊂ R 3, we consider maps n: R 3\G→ S 2 minimizing the
energy E (n)=∫ R 3\G|∇ n| 2+ F s (n⌊∂ G) among S 2-valued map such that n (x)≈ n 0 as …

Polydispersity and surface energy strength in nematic colloids

G Canevari, A Zarnescu - arXiv preprint arXiv:1910.03342, 2019 - arxiv.org
We consider a Landau-de Gennes model for a polydisperse, inhomogeneous suspension of
colloidal inclusions in a nematic host, in the dilute regime. We study the homogenised limit …

Quantum-dots-dispersed bent-core nematic liquid crystal and cybotactic clusters: experimental and theoretical insights

S Patranabish, Y Wang, A Sinha, A Majumdar - Physical Review E, 2021 - APS
We study a quantum-dots (QDs) dispersed bent-core nematic liquid crystalline system in
planar geometry and present experimental measurements of the birefringence (Δ n), order …

Two-dimensional ferronematics, canonical harmonic maps and minimal connections

G Canevari, A Majumdar, B Stroffolini… - Archive for Rational …, 2023 - Springer
We study a variational model for ferronematics in two-dimensional domains, in the “super-
dilute” regime. The free energy functional consists of a reduced Landau-de Gennes energy …

Colloidal Homogenisation for the Hydrodynamics of Nematic Liquid Crystals

F De Anna, A Schloemerkemper… - arXiv preprint arXiv …, 2024 - arxiv.org
This paper analytically explores a simplified model for the hydrodynamics of nematic liquid
crystal colloids. We integrate a Stokes equation for the velocity field with a Ginzburg-Landau …

Topics in the mathematical design of materials

X Chen, I Fonseca, M Ravnik… - … of the Royal …, 2021 - royalsocietypublishing.org
We present a perspective on several current research directions relevant to the
mathematical design of new materials. We discuss:(i) design problems for phase …

[PDF][PDF] Mathematical Analysis of Soft Matter

D Beller, L Bronsard, C Calderer, A Zarnescu - 2024 - stats.birs.ca
Soft matter comprises a variety of physical systems that can be structurally altered by small
stresses of the magnitude comparable to thermal fluctuations. They encompass a wide …
