Résumé
On décrit les phonons, les phasons et les dislocations comme des distorsions et changements de disposition des mailles. On démontre la relation entre le modèle des mailles de ces défauts et celui des ondes de densité. On discute la déformation et la relaxation des variables des phasons dans le modèle des mailles.
Abstract
Phonons, phasons and dislocations in a quasicrystal are interpreted as distortions and rearrangements of unit cells. The relation between the unit cell picture these defects and a simple density wave picture is demonstrated. Phason strain and relaxation is discussed in the context of the unit cell picture.
