Topological decomposition and transformation of photonic quasicrystals. [PDF]

Nanophotonics
Photonic quasicrystals, generated through the interference of multiple vortex beams, exhibit rich and complex topological landscapes. However, unlike their periodic counterparts, they have far lacked the same level of controllability and ...

Quasicrystal synthesis by shock compression. [PDF]

Commun Chem
Quasicrystals are of interest because of their unique nonperiodic structures and physical properties. Motivated by naturally occurring icosahedral AlCuFe- and decagonal AlNiFe-phases hosted in a shocked meteorite, different laboratories have undertaken a

Hierarchical ground-state crystals underlying Hertzian quasicrystals. [PDF]

Nat Commun
As a simple physics model for crystal and quasicrystal formation, the Hertzian potential describes the interaction between two soft-core colloidal particles.

Comprehensive experimental datasets of quasicrystals and their approximants. [PDF]

Sci Data
Quasicrystals are solid-state materials that typically exhibit unique symmetries, such as icosahedral or decagonal diffraction symmetry. They were first discovered in 1984.

Robust flat bands in twisted trilayer graphene moiré quasicrystals. [PDF]

Nat Commun
Moiré structures formed by twisting three layers of graphene with two independent twist angles present an ideal platform for studying correlated quantum phenomena, as an infinite set of angle pairs is predicted to exhibit flat bands.

Heptagonal quasicrystals: Construction of 2D lattices and demonstrations using laser pointers – Concluding part

Macedonian Journal of Chemistry and Chemical Engineering, 2023
Photographic slides of an aperiodic heptagonal tiling were used as two-dimensional diffraction gratings (as a standard approach) to describe and demonstrate the basic properties of dodecagonal quasicrystals.

On the Constitutive Modelling of Piezoelectric Quasicrystals

Crystals, 2023
Quasicrystals endowed with piezoelectric properties belong nowadays to novel piezoelectric materials. In this work, the basic framework of generalized piezoelectricity theory of quasicrystals is investigated by providing an improvement of the existing ...

Topological critical states and anomalous electronic transmittance in one-dimensional quasicrystals

Physical Review Research, 2021
Due to the absence of periodic length scale, electronic states and their topological properties in quasicrystals have been barely understood. Here, we focus on one-dimensional quasicrystals and reveal that their electronic critical states are ...

Defects in Static Elasticity of Quasicrystals

Crystals, 2017
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 ...
