| contents | Disordered hyperuniform many-particle systems are recently discovered exotic states of matter, characterized by a complete suppression of normalized infinite-wavelength density fluctuations and lack of conventional long-range order. Here, we begin a program to quantify the structural properties of nonhyperuniform and hyperuniform networks. In particular, large two-dimensional (2D) Voronoi networks (graphs) containing approximately 10,000 nodes are created from a variety of different point configurations, including the antihyperuniform HIP, nonhyperuniform Poisson process, nonhyperuniform RSA saturated packing, and both non-stealthy and stealthy hyperuniform point processes. We carry out an extensive study of the Voronoi-cell area distribution of each of the networks through determining multiple metrics that characterize the distribution, including their higher-cumulants. We show that the HIP distribution is far from Gaussian; the Poisson and non-stealthy hyperuniform distributions are Gaussian-like distributions, the RSA and the highest stealthy hyperuniform distributions are also non-Gaussian, with diametrically opposite non-Gaussian behavior of the HIP. Moreover, we compute the Voronoi-area correlation functions $C_{00}(r)$ for the networks [M. A. Klatt and S. Torquato, Phys. Rev. E {\bf 90}, 052120 (2014)]. We show that the correlation functions $C_{00}(r)$ qualitatively distinguish the antihyperuniform, nonhyperuniform and hyperuniform Voronoi networks. We find strong anticorrelations in $C_{00}(r)$ (i.e., negative values) for the hyperuniform networks. |
