Distortional Lifshitz Vectors and Helicity in Nematic Free Energy
Density [PDF]
Amelia Carolina SparavignaHere we discuss the free energy of nematic liquid crystals using two vectors and the helicity, with the aim of having a compact form of its density. The two vectors are due to the splay and bend distortions of the director field. They have a polar nature, whereas the helicity is a pseudoscalar.View original: http://arxiv.org/abs/1207.2918
