Orientation Waves in Colloidal Crystals

Crystals are usually thought of as the condensation of density waves.  However, in some systems, notably blue phase liquid crystals, and, according to recent results in our group also hard tetrahedra, the formation of a crystal comes from the condensation of an “Orientation Wave” in which theorientation of the constituent parts vary periodically, and this periodic variation condenses.  …Read more.
