Quantum Spin Hall Effect and Spin Bott Index in a Quasicrystal Lattice. [PDF]

Physical Review Letters, 2018
Despite the rapid progress in the field of the quantum spin Hall (QSH) effect, most of the QSH systems studied up to now are based on crystalline materials. Here we propose that the QSH effect can be realized in quasicrystal lattices (QLs).

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.

Three-Dimensional Axisymmetric Analysis of Annular One-Dimensional Hexagonal Piezoelectric Quasicrystal Actuator/Sensor with Different Configurations

Crystals
The presented article is about the axisymmetric deformation of an annular one-dimensional hexagonal piezoelectric quasicrystal actuator/sensor with different configurations, analyzed by the three-dimensional theory of piezoelectricity coupled with phonon

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.

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 ...

Forced vibration analysis of inhomogeneous quasicrystal coating in a thermal environment

Frontiers in Materials, 2022
The tremendous attention of researchers has been attracted to the unusual properties of quasicrystals in coatings. In this paper, the exact solutions of the functionally graded multilayered two-dimensional quasicrystal coating structures in a thermal ...

Observation of a Time Quasicrystal and Its Transition to a Superfluid Time Crystal. [PDF]

Physical Review Letters, 2017
We report experimental realization of a quantum time quasicrystal and its transformation to a quantum time crystal. We study Bose-Einstein condensation of magnons, associated with coherent spin precession, created in a flexible trap in superfluid ^{3}He ...

Quasicrystals

Journal of Non-Crystalline Solids, 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.

Emission Characteristics of Lasing From all Organic Mirrorless Quasicrystal

IEEE Photonics Journal, 2016
We demonstrate the emission characteristics, including polarization property and temperature effect, of lasing from all organic mirrorless quasicrystal fabricated by seven-beam interference.

Ageing of Al-Mn-Cu-Be Alloys for Stimulating Precipitation of Icosahedral Quasicrystals

Metals, 2020
In this work, the ageing of some Al-Mn-Cu-Be alloys was investigated in the temperature range in which predominantly icosahedral quasicrystalline (IQC) precipitates can form.
