From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Dynamics of particle flips in two-dimensional quasicrystals

, 2010
The dynamics of quasicrystals is more complicated than the dynamics of periodic solids and difficult to study in experiments. Here, we investigate a decagonal and a dodecagonal quasicrystal using molecular dynamics simulations of the Lennard-Jones-Gauss ...

Phonon-phason coupling in icosahedral quasicrystals [PDF]

, 1998
From relaxation simulations of decoration-based quasicrystal structure models using microscopically based interatomic pair potentials, we have calculated the (usually neglected) phonon-phason coupling constant.

Synthesis, Structures, and Transport Properties of Quaternary Ba–Ag–Tr–As Materials (Tr = Ga, In)

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 9, June 24, 2025.
The synthesis, structures, and properties of two triel‐containing quaternary arsenides are investigated. The synthesis, structures, and properties of two quaternary barium–arsenide materials are presented. The first, Ba4Ag2.3In1.7As8, is a novel material with the monoclinic unit cell (P21/m space group).

Three-Dimensional Icosahedral Phase Field Quasicrystal. [PDF]

Physical Review Letters, 2016
We investigate the formation and stability of icosahedral quasicrystalline structures using a dynamic phase field crystal model. Nonlinear interactions between density waves at two length scales stabilize three-dimensional quasicrystals. We determine the

First-order localization and quantum phase transition induced by quasicrystal imaginary domain

Physical Review Research
The non-Hermitian extension of quasicrystals provides a highly tunable system for exploring novel material phases. While extended-localized phase transitions have been observed in one dimension, quantum phase transitions in higher dimensions and various ...

Computation and visualization of photonic quasicrystal spectra via Blochs theorem

, 2008
Previous methods for determining photonic quasicrystal (PQC) spectra have relied on the use of large supercells to compute the eigenfrequencies and/or local density of states (LDOS).

Frustration and thermalization in an artificial magnetic quasicrystal [PDF]

Nature Physics, 2017
Artificial frustrated systems offer a playground to study the emergent properties of interacting systems. Most work to date has been on spatially periodic systems, known as artificial spin ices when the interacting elements are magnetic.

QUASICRYSTALS

Le Journal de Physique Colloques, 1985
We introduce the concept of quasicrystals and discuss their diffraction patterns. The idea of local isomorphism is argued to be a physically meaningful one.

Localized and Extended Phases in Square Moiré Patterns

Annalen der Physik, Volume 537, Issue 6, June 2025.
Rotated superimposed lattices in two dimensions, the termed moiré patterns, represent a clear example of how the structure affects the physical properties of a particle moving on it. A robust numerical treatment of continuous and discrete models leads to confirm that while localized states result from angles that produce non‐commensurable lattices ...
