Comment on "Structure factors of harmonic and anharmonic Fibonacci chains by molecular dynamics simulations"

TL;DR

This paper critiques a recent study on phonon broadening in Fibonacci chains, highlighting inaccuracies and contradictions in the original analysis based on molecular dynamics simulations.

Contribution

It provides a critical reassessment of previous claims about phonon behavior in Fibonacci chains, clarifying misconceptions and correcting factual inaccuracies.

Findings

Identifies errors in previous molecular dynamics interpretations

Clarifies the true nature of phonon broadening in Fibonacci chains

Challenges assumptions made in the original study

Abstract

Recently, Engel et al. discussed phonon broadening as observed in 3D quasicrystals on the basis of calculations on the Fibonacci chain. We show that the paper contains several statements and assumptions that are contradicted by factual truth.
