Comment on "Sound Modes broadening in Quasicrystals"
G. Coddens
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 glas…

On the problem of the correct interpretation of phason elasticity in quasicrystals
G. Coddens
Recently Francoual et al. claimed to have observed the dynamics of long-wavelength phason fluctuations in i-AlPdMn quasicrystals. We will show that the data reported call for a mor…

More on "Atomic jumps in quasiperiodic AlNiCo and related crystalline material"
G. Coddens
We strongly disagree with a number of statements by Dolin{š}ek et al. about phason dynamics in quasicrystals (QCs).

More on``Atomic motions in the crystalline AlCuNi alloy''
Gerrit Coddens
We refute recent claims that ultrafast atomic jumps as observed in quasicrystals (QC) could be called phasons in many crystalline alloys by pointing out that there is a genuine con…
