Twisted bilayer graphene’s gallery of phases

Physics Today
The simultaneous occurrence of exotic phases, and the ability to easily tune them, has positioned magic-angle twisted bilayer graphene as one of the richest materials platforms in condensed-matter physics.

Evidence for An Hexagonal Phase in Twisted Nematics

Molecular Crystals and Liquid Crystals, 1978
Abstract Sequences of microscopic photographies show different behaviors during the isotropic-cholesteric transition in a binary diagram untwisted nematic-cholesterol ester. For certain conditions, a mosaǐc texture arises between the isotropic liquid and the focal-conic texture, the germination of which gives evidence for an hexagonal symmetry.

Twist Grain Boundary (TGB) Phases

2007
Chirality in self-organizing media can yield a variety of novel mesophases with unique properties and structures. At high levels of chirality, however, non-linear effects come into play. The effects of chirality in self-assembled structures can compete successfully with those of conventional self-assembling properties to yield frustrated structures ...
