Comment on "Atomic jumps in quasiperiodic Al$_{72.6}$Ni$_{10.5}$Co$_{16.9}$ and related crystalline material"

TL;DR

This paper critically examines claims about phason dynamics in quasicrystals, challenging previous assertions and providing a different perspective on atomic jump behavior in these materials.

Contribution

It offers a critical commentary that disputes prior statements regarding the uniqueness of phason dynamics in quasicrystals.

Findings

Questions the specificity of phason dynamics in QCs

Highlights differences in atomic jump mechanisms

Provides alternative interpretation of experimental data

Abstract

We disagree with a number of statements by Dolinsek et al. about the specificity of phason dynamics in quasicrystals (QCs).
