Dynamic Cubic Instability in a 2D Q-tensor Model for Liquid Crystals

Analysis of PDEs 2015-01-22 v2

Abstract

We consider a four-elastic-constant Landau-de Gennes energy characterizing nematic liquid crystal configurations described using the QQ-tensor formalism. The energy contains a cubic term and is unbounded from below. We study dynamical effects produced by the presence of this cubic term by considering an L2L^2 gradient flow generated by this energy. We work in two dimensions and concentrate on understanding the relations between the physicality of the initial data and the global well-posedness of the system.
