报告摘要: Quasicrystals are important ordered structures in materials. Compared with periodic crystal, quasicrystals do not possess translational symmetry, but have orientational symmetry. After about 30 years of during efforts, a lot of problems, such as the position of the quasi-lattice sites, the diffraction of quasicrystals, have been solved. However, there still exist unsolved problems, such as the stability of quasicrystals, the difference between soft- and hard-quasicrystals. Solving these problems requires the combination of physical understanding, mathematical analysis, and novel computational methods. In this talk, we will give a short review about quasicrystals, and introduce our projection method and applications to a class of coarse-grained phase field crystal models with two scales.
