研究了具有5倍对称性和10倍对称性的可能软物质准晶体的动力学和波传播。在物质流体动力学的研究中,除了基本激励声子和相子外,还引入了流体声子,这一概念起源于朗道学派。软物质准晶体与固体准晶体的本质区别在于流体声子的存在以及流体声子、声子和相子之间的相互作用。在Lubensky等人提出的固体准晶体流体力学理论的基础上,提出了软物质准晶体流体力学理论,并通过有限差分法给出了数值实现。本文的结果探讨了具有5倍和10倍对称性的软物质准晶体的一些动力学和波传播行为。
The dynamics and wave propagation of possible soft-matter quasicrystals with 5- and 10-fold symmetries are studied. Apart from elementary excitations – phonons and phasons, the fluid phonon is introduced in the study for the hydrodynamics of the matter, which was originated from the Landau school. The essential difference of soft-matter quasicrystals with solid quasicrystals lies in the existence of fluid phonon and the interaction between fluid phonon, phonons and phasons. By extending the hydrodynamics theory of solid quasicrystals proposed by Lubensky et al. the hydrodynamics theory of soft-matter quasicrystals is suggested, and we give a numerical implementation through finite difference method. The results in this paper explore some dynamic and wave propagating behaviour of soft-matter quasicrystals with 5- and 10-fold symmetries.
