Distortional Lifshitz Vectors and Helicity in Nematic Free Energy Density

International Journal of Sciences, 2013, vol. 2, issue 07, 54-59

Abstract: Here 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.
