Is it true that a phason is a Goldstone mode?
Yes. Multiple physics references and peer-reviewed studies establish that a phason is a Goldstone mode (or Nambu-Goldstone boson) arising from spontaneously broken continuous symmetries, such as translational symmetry in aperiodic crystals or phase symmetry in liquid crystals.
