Structural Disorder in Quasicrystals [PDF]
One of the challenges of modern crystallography of complex systems (complex metallic alloys, proteins, aperiodic crystals and quasicrystals) is to properly describe the disorder in these systems and discuss correctly the refinement results in terms of ...

Data-Driven Design and Fabrication of Heat-Resistant, Ultrastrong, Lightweight Aluminum-Based Entropy Alloy by Additive Manufacturing. [PDF]
A data‐driven strategy integrating quantum machine learning (QML) and high‐throughput computing overcomes hot‐cracking limitation to design a novel lightweight aluminum‐based entropy alloy for additive manufacturing. The fabrication transforms brittle intermetallics into deformable hierarchical nanostructures, yielding ultrastrong strength (>1 GPa) and

Three-Dimensional and Two-Dimensional Green Tensors of Piezoelectric Quasicrystals
In this work, within the framework of the linear piezoelectricity theory of quasicrystals, the three-dimensional and two-dimensional Green tensors for arbitrary piezoelectric quasicrystals are derived.

Robust Anderson transition in non-Hermitian photonic quasicrystals [PDF]
Anderson localization, i.e. the suppression of diffusion in lattices with random or incommensurate disorder, is a fragile interference phenomenon which is spoiled out in the presence of dephasing effects or fluctuating disorder.

Large spatial Goos-Hänchen shifts from quasicrystals with graphene
We investigate the spatial Goos-Hänchen (GH) shift of reflected beam from quasicrystals composed of Fibonacci dielectrics and graphene. The quasicrystals are composed of two symmetrical Fibonacci dielectrics and graphene is embedded in the center of the ...

Precipitation of multi-type nano-quasicrystals in a Mg-Zn-Y alloy
Mg-6Zn-1Y (at.%) ribbons with strengthening precipitates of multi-type nanoquasicrystals were prepared by melt-spinning followed by aging treatments. Microstructural evolution of the rapidly solidified ribbons during isothermal aging was comprehensively ...

There are several incentives to identify the analogues of dislocations and disclinations in quasicrystals. Penrose patterns are two-dimensional systems, and according to phase space counting fluctuations of the atomic displacements are so strong that exact long-range order is reduced to quasi-longrange order just as in periodic crystals.

One long-standing and crucial issue in the study of quasicrystals has been to identify the physical properties characteristic of quasicrystals. The large positive temperature coefficient of thermal conductivity at temperatures above room temperature ...
