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.…

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…
