Abstract

Quasicrystals (QCs) are long-range ordered materials but are not periodic. Their diffraction pattern displays sharp Bragg peaks as a signature of the long-range order but with rotational symmetries incompatible with lattice periodicity. Quasiperiodicity yields new, long-wavelength excitations called phasons, which are diffusive modes. In this chapter we review the experimental results providing evidence ...
