Exact and approximate solutions for elastic interactions in a nematic liquid crystal
TGJ Chandler, SE Spagnolie - SIAM Journal on Applied Mathematics, 2024 - SIAM
Anisotropic fluids appear in a diverse array of systems, from liquid crystal displays to
bacterial swarms, and are characterized by orientational order. Large colloidal particles …

Defect pairs in nematic cell alignment on doubly connected domains
H Miyazako, T Sakajo - Proceedings A, 2024 - royalsocietypublishing.org
We consider the orientational order that arises from the alignment of anisotropic biological
cells confined in bounded domains. Especially, it is known that topological defects, where …

Viscous tweezers: controlling particles with viscosity
Control of particle motion is generally achieved by applying an external field that acts
directly on each particle. Here, we propose a global way to manipulate the motion of a …

Rigid and deformable bodies in nematic liquid crystals
TGJ Chandler, SE Spagnolie - Physical Review Fluids, 2024 - APS
A nematic liquid crystal, a phase of matter composed of rodlike molecules, exhibits a
tendency towards uniform molecular alignment. Bodies inserted into such a fluid can disturb …

Active nematic response to a deformable body or boundary: elastic deformations and anchoring-induced flow
TGJ Chandler, SE Spagnolie - arXiv preprint arXiv:2409.15617, 2024 - arxiv.org
A body immersed in a nematic liquid crystal disturbs the fluid's preferred molecular
configuration and increases its stored elastic energy. In an active nematic, the fluid …

Free energy formulae for confined nematic liquid crystals based on analogies with Kirchhoff–Routh theory in vortex dynamics
H Miyoshi, H Miyazako, T Nara - Proceedings A, 2024 - royalsocietypublishing.org
Active nematics are influenced by alignment angle singularities called topological defects.
The localization of these defects is of major interest for biological applications. The total …
