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...
