Columnar Phases of Liquid Crystals
The columnary phase of liquid crystals or discotics is a phase where translational invariance is broken in two directions. In other words, it is possible to say that a columnar phase is a system of columns, forming a regular two-dimensional lattice. However, molecules array along each column without any long-range order, which makes it possible for columns to glide with respect to each other in a liquidlike manner. The second name of the columnar phase (discotic) is accounted for by the fact that all so-far known columnar phases are comprised of disk-like molecules. In this chapter, for brevity, we will often use the word discotics instead of the full title—columnar phases of liquid crystals.
