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...

A Mean Field Model For the Coexistence of Nematic, Smectic A and Smectic C phases in Liquid Crystals
Nematic Smectic C Smectic A Liquid Crystals
2010/4/16
We present here a mean field model for the nematic-smectic A-smectic C coexistence of a liquid crystal near the NAC point which is a multicritical point. The critical exponents calculated from our mod...
