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…
