TLDR
In this article, a simple decoration of the Penrose tiling is used to produce a two-dimensional quasi-crystalline model, which undergoes a first-order transition to the liquid phase.Abstract:
We propose a simple decoration of the Penrose tiling to produce a two-dimensional quasi-crystalline model. We have used molecular dynamics simulation to invesigate the stability and the phase transitions of this system. Stable with pair potentials, it undergoes a first-order transition to the liquid phase. Its enthalpy is below the enthalpy of the quenched glassy state.read more

Strain localization and percolation of stable structure in amorphous solids.
Yunfeng Shi,Michael L. Falk +1 more
TL;DR: Spontaneous strain localization occurs during mechanical tests of a model amorphous solid simulated using molecular dynamics, and the authors infer the existence of a related microstructural length scale.

Mosaic two-lengthscale quasicrystals
TL;DR: Two-dimensional hard disks decorated with step-like square-shoulder repulsion that mimics, for example, the soft alkyl shell around the aromatic core in dendritic micelles are studied, finding a family of quasicrystals with 10-, 12-, 18- and 24-fold bond orientational order which originate from mosaics of equilateral and isosceles triangles formed by particles arranged core-to-core and shoulder- to-sh shoulder.
