Nematic liquid crystals (NLCs) are anisotropic material intermediate that combines the fluidity of liquids with the orientational order of solids. NLCs are best known for their applications in the thr...
The helical phase of chiral nematic liquid crystals as the Bianchi VII(0) group manifold
The helical phase chiral nematic liquid crystals the Bianchi VII(0) group manifold
2011/9/13
We show that the optical structure of the helical phase of a chiral nematic is naturally associated with the Bianchi V II0 group manifold, of which we give a full account. The Joets-Ribotta metric gov...
