The discretely diffracting aperiodic crystals termed quasicrystals, discovered at NBS in the early 1980s, have led to much interdisciplinary activity involving mainly materials science, physics, mathematics, and crystallography. It led to a new understanding of how atoms can arrange themselves, the role of periodicity in nature, and has created a new ...

Defects in Static Elasticity of Quasicrystals [PDF]
A review on mathematical elasticity of quasicrystals is given. In this review, the focus is on various defects of quasicrystals. Dislocation and crack are two classes of typical topological defects, while their existence has great influence on the ...

Line Defects in Two-Dimensional Dodecagonal Quasicrystals [PDF]
In this work, line defects in two-dimensional dodecagonal quasicrystals are investigated. Using the ten-dimensional framework of the integral formalism of two-dimensional quasicrystals, the closed-form solutions for the displacement fields and stress ...

Line Defects in Quasicrystals [PDF]
The six-dimensional framework of the integral formalism for line defects (straight dislocations and line forces) in anisotropic elasticity has been extended to a 2n-dimensional integral formalism for line defects in quasicrystals (n=4,5,6 for one-, two-,

The Ammann-Kramer-Neri tiling model of a P-ZnMgEr Bergman-type quasicrystal based on in-house X-ray diffraction. [PDF]
A structural solution is presented of a primitive icosahedral ZnMgEr quasicrystal representing the Bergman‐type family. The structure model is based on atomic decoration of the Ammann–Kramer–Neri tiling.This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in‐house X‐ray diffraction and the

Disclinations in quasicrystals [PDF]
The most significant feature in the transition from the quasicrystalline to the amorphous state is the loss of long-range bond-orientational order. Disclinations are candidates for elementary excitations which destroy angular correlations. Generalizing the topological defect classification, we investigate point singularities in two-dimensional ...
