Interface crack between dissimilar one-dimensional hexagonal quasicrystals with piezoelectric effect [PDF]

, 2019
In this paper, an interface crack between dissimilar one-dimensional (1D) hexagonal quasicrystals with piezoelectric effect under anti-plane shear and in-plane electric loadings is studied. By using integral transform techniques, the mixed boundary value

Numerical Methods for Quasicrystals [PDF]

, 2013
Quasicrystals are one kind of space-filling structures. The traditional crystalline approximant method utilizes periodic structures to approximate quasicrystals.

Topological Photonic Quasicrystals: Fractal Topological Spectrum and Protected Transport

Physical Review X, 2016
We show that it is possible to have a topological phase in two-dimensional quasicrystals without any magnetic field applied, but instead introducing an artificial gauge field via dynamic modulation.

Microstructure and Nanoindentation Behavior of Ti₄₀Zr₄₀Ni₂₀ Quasicrystal Alloy by Casting and Rapid Solidification

Metals, 2021
A Ti40Zr40Ni20 quasicrystal (QCs) rod and ribbons were prepared by conventional casting and rapid solidification. The X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential scanning ...

Precipitation of binary quasicrystals along dislocations

Nature Communications, 2018
Quasicrystal precipitation in alloys should be favored at dislocations, which break crystal symmetry, but almost all precipitates at dislocations are periodic.

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.

Imaging quasiperiodic electronic states in a synthetic Penrose tiling

Nature Communications, 2017
Quasicrystals possess long-range order but lack translational symmetry. Here, the authors use atomic manipulation and scanning tunnelling microscopy to assemble a Penrose tiling quasicrystal and observe that its electronic density of states has a ...

Self-induced Bose glass phase in quantum quasicrystals

Results in Physics
We study the emergence of Bose glass phases in self sustained bosonic quasicrystals induced by a pair interaction between particles of Lifshitz–Petrich type.

New group of stable icosahedral quasicrystals: structural properties and formation conditions

, 2003
Structural studies on the icosahedral quasicrystals in Zn-Mg-Sc, Cu-Ga-Mg-Sc, and Zn-Mg-Ti alloys as well as their corresponding 1/1 cubic approximants, have revealed that these quasicrystals belong to a new structural group similar to Cd-based ...
