Spectral Distribution of one-dimensional Photonic Quasicrystals: The Role of Irrational Numbers
Hui Quan, Wei Si, Kai Jiang
In this paper, we construct a one-dimensional photonic quasicrystal by combining two incommensurate spatial harmonics, where the ratio of their periods is the irrational number β.…
Efficient numerical methods for computing stationary states of spherical Landau-Brazovskii model
Qun Qiu, Wei Si, Guanghua Ji +1
In this paper, we develop a set of efficient methods to compute stationary states of the spherical Landau-Brazovskii (LB) model in a discretization-then-optimization way. First, we…
Designing a minimal Landau theory to stabilize desired quasicrystals
Wei Si, Shifeng Li, Pingwen Zhang +2
Interparticle interactions with multiple length scales play a pivotal role in the formation and stability of quasicrystals. Choosing a minimal set of length scales to stabilize a g…
Tilt grain boundaries of hexagonal structures: a spectral viewpoint
Kai Jiang, Wei Si, Jie Xu
We propose a spectral viewpoint for grain boundaries that are generally quasiperiodic. To accurately capture the spectra computationally, it is crucial to adopt the projection meth…
High-order energy stable schemes of incommensurate phase-field crystal model
