Title: Mathematical analysis of a model for ferronematics in two dimensions
Abstract: Ferronematics are composite materials characterised by the coupling
between magnetic particles and nematic liquid crystals. In this talk, I will present
some results on a two-dimensional model for ferronematics in confined geome-
tries. The model is based on the coupling between a polar order parameter - the
magnetisation vector, which describes the magnetic inclusions - and a nonpo-
lar one - the Landau-de Gennes Q-tensor, which describes the liquid crystal
matrix. We will discuss the qualitative behaviour of free-energy minimisers in
some asymptotic regimes of parameters, where both point and line singulari-
ties appear. The talk is based on joint work with Giacomo Canevari, Federico Dipasquale, Apala Majumdar and Yiwei Wang.
