Comment on "Sound Modes broadening in Quasicrystals"

TL;DR

This paper critiques de Boissieu et al.'s explanation for acoustic mode broadening in quasicrystals, arguing that their model, borrowed from glasses, is not applicable to QC and discusses publication suppression issues.

Contribution

It provides a critical analysis of the applicability of a glass-based model to quasicrystals and discusses challenges faced in publishing such critiques.

Findings

The proposed model is not suitable for quasicrystals.

There are fundamental objections to applying glass models to QC.

Publication suppression issues are addressed.

Abstract

Recently de Boissieu et al. proposed an explanation for the broadening of acoustic modes observed in quasicrystals (QC). It is the transcription of a well-known model used for glasses. We raise two fundamental objections against applying it to QC. After the text of the Comment we report the methodology that has been used to thwart the publication of this Comment, which is perfectly valid.
