Smectic Phases with Cubic Symmetry: The Splay Analog of the Blue Phase
B. A. DiDonna, Randall D. Kamien
Abstract
We report on a construction for smectic blue phases, which have quasi-long range smectic translational order as well as long range cubic or hexagonal order. Our proposed structures fill space with a combination of minimal surface patches and cylindrical tubes. We find that for the right range of material parameters, the favorable saddle-splay energy of these structures can stabilize them against uniform layered structures.
