The two-phase twisted-ring counter circuit

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
The behavior of the two-phase twisted-ring counter (2P-TRC) circuit is analyzed. The circuit produces two individual phased clock signals that exercise a phase difference equal to the half period of the clock. A tree-like structure is built by applying the phased outputs of the circuit to the clock inputs of two replicas of the circuit in order to ...

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 ...

Z2topological phase transition in twisted plumbene.

Journal of physics. Condensed matter : an Institute of Physics journal
Since the discovery of superconductivity in twisted bilayer graphene, which initiated the field of twistronics, Moiré patterns caused by different twisting angles between stacked layers of van der Waals 2D materials show unique properties in these structures.
