Uniform asymptotics and entropy structure of the Bingham distribution in arbitrary dimensions
Dawei Wu, Lei Zhang, Pingwen Zhang
The Bingham distribution is widely used to model directional data with antipodal symmetry, and its normalizing constant and moments play a central role in statistical inference…

Phason-Driven Diversity of Nucleation Pathways in Icosahedral Quasicrystals
Gang Cui, Lei Zhang, Pingwen Zhang +2
The nucleation of quasicrystals remains a fundamental puzzle, primarily due to the absence of a periodic translational template. Here, we demonstrate that phasons - hidden degrees…

From molecular model to tensor model of nematic liquid crystals through entropy decomposition
Baoming Shi, Dawei Wu, Lei Zhang +1
In the mathematical modeling of nematic liquid crystals, a practical and physically reliable -tensor model can be derived from Onsager's molecular model with the Bingha…
