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]

Communications Chemistry
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

Comprehensive experimental datasets of quasicrystals and their approximants [PDF]

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

Spin dynamics, loop formation and cooperative reversal in artificial quasicrystals with tailored exchange coupling [PDF]

Communications Physics, 2023
Aperiodicity and un-conventional rotational symmetries allow quasicrystalline structures to exhibit unusual physical and functional properties. In magnetism, artificial ferromagnetic quasicrystals exhibited knee anomalies suggesting reprogrammable ...

Hierarchical ground-state crystals underlying Hertzian quasicrystals [PDF]

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

Image Sampling with Quasicrystals [PDF]

Symmetry, Integrability and Geometry: Methods and Applications, 2009
We investigate the use of quasicrystals in image sampling. Quasicrystals produce space-filling, non-periodic point sets that are uniformly discrete and relatively dense, thereby ensuring the sample sites are evenly spread out throughout the sampled image.

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

Nature Communications
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.

Deep Learning Enables Rapid Identification of a New Quasicrystal from Multiphase Powder Diffraction Patterns [PDF]

Advanced Science
Since the discovery of the quasicrystal, approximately 100 stable quasicrystals are identified. To date, the existence of quasicrystals is verified using transmission electron microscopy; however, this technique requires significantly more elaboration ...

Fascinating quasicrystals [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 2007
It took Dan Shechtman more than two years to get his discovery of an Al–Mn phase with icosahedral diffraction symmetryandsharp Bragg reflections published. A paradigm shift had to take place before this novel ordering state of matter – seemingly contradicting crystallographic laws – could be accepted.
