| 中文摘要 | General theory of diffuse scattering of quasicrystals at high temperature due to thermally equilibrated phonon and phason fluctuations has been developed using three different methods. These methods give same results and these results are modifications of those put forward by Jaric and Nelson [Phys. Rev. B 37, 4458 (1988)]. The formulas derived here are not limited to simple quasilattice and may be used for any decorated quasicrystals. At low temperature T, phonon fluctuation is equilibrated under frozen phason-type displacement field. By supposing that this frozen phason-type field was equilibrated at some high temperature T-q (quenched phasons), formulas of diffuse scattering at T are derived. These formulas evolve automatically into those of thermally equilibrated phasons when T is equal to T-q. |
