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 …

Modelling and computation of liquid crystals

W Wang, L Zhang, P Zhang - Acta Numerica, 2021 - cambridge.org
Liquid crystals are a type of soft matter that is intermediate between crystalline solids and
isotropic fluids. The study of liquid crystals has made tremendous progress over the past four …

Spherical Particle in Nematic Liquid Crystal with a Magnetic Field and Planar Anchoring

L Bronsard, D Louizos, D Stantejsky - Journal of Nonlinear Science, 2025 - Springer
We study minimizers of the Landau-de Gennes energy in R 3\B 1 (0) with external magnetic
field in the large particle limit. We impose strong tangential anchoring and uniaxiality of the …

Line defects in the small elastic constant limit of a three-dimensional Landau-de Gennes model

We consider the Landau-de Gennes variational model for nematic liquid crystals, in three-
dimensional domains. More precisely, we study the asymptotic behaviour of minimizers as …
