Stability of Two-Dimensional Soft Quasicrystals

, 2015
The relative stability of two-dimensional soft quasicrystals is examined using a recently developed projection method which provides a unified numerical framework to compute the free energy of periodic crystal and quasicrystals. Accurate free energies of

Formation of a stable deacagonal quasicrystalline Al-Pd-Mn surface layer [PDF]

, 2001
We report the in situ formation of an ordered equilibrium decagonal Al-Pd-Mn quasicrystal overlayer on the 5-fold symmetric surface of an icosahedral Al-Pd-Mn monograin.

Line Defects in Two-Dimensional Dodecagonal Quasicrystals

Mathematics
In this work, line defects in two-dimensional dodecagonal quasicrystals are investigated. Using the ten-dimensional framework of the integral formalism of two-dimensional quasicrystals, the closed-form solutions for the displacement fields and stress ...

Large spatial Goos-Hänchen shifts from quasicrystals with graphene

Results in Physics, 2020
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 ...

Quantum transport in quasicrystals and complex metallic alloys [PDF]

, 2007
The semi-classical Bloch-Boltzmann theory is at the heart of our understanding of conduction in solids, ranging from metals to semi-conductors. Physical systems that are beyond the range of applicability of this theory are thus of fundamental interest ...

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.

Proliferation of anomalous symmetries in colloidal monolayers subjected to quasiperiodic light fields

, 2010
Quasicrystals provide a fascinating class of materials with intriguing properties. Despite a strong potential for numerous technical applications, the conditions under which quasicrystals form are still poorly understood.

Precipitation of multi-type nano-quasicrystals in a Mg-Zn-Y alloy

Journal of Magnesium and Alloys
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 ...

Stability of Quasicrystals Composed of Soft Isotropic Particles

, 2011
Quasicrystals whose building blocks are of mesoscopic rather than atomic scale have recently been discovered in several soft-matter systems. Contrary to metallurgic quasicrystals whose source of stability remains a question of great debate to this day ...

Large-scale database analysis of anomalous thermal conductivity of quasicrystals and its application to thermal diodes

Science and Technology of Advanced Materials: Methods
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 ...
