Abstract
Studies on phason modes in quasicrystals, but more generally in aperiodic phases, which encompass incommensurately modulated phases, composites and quasicrystals, are reviewed. After an introduction on phason modes in aperiodic phases, the hydrodynamic theory is presented. The case of incommensurately modulated phases is illustrated by results on ThBr4. Atomic models used to simulate phason modes in quasicrystals are then presented, followed by an overview of results obtained for icosahedral and decagonal phases.
