Abstract
Provided here are ensembles of two-dimensional stealthy hyperuniform point patterns (configurations) with χ = 0.2, 0.4, and 0.48 generated using the collective-coordinate optimization scheme under periodic boundary conditions. Each file corresponds to a single configuration with N rows and two columns where N is the number of points in the configuration. The first column corresponds to the x coordinate of the point and the second column corresponds to the y coordinate. The points are contained in a square box with side length √N.

Description of the data and file structure
Provided here are ensembles of two-dimensional stealthy hyperuniform point patterns with χ = 0.2, 0.4, and 0.48 generated using the collective-coordinate optimization scheme under periodic boundary conditions. Each file contains the x and y coordinates of each particle in a particular stealthy hyperuniform point pattern. This data was used to create the tessellations analyzed in Figs. 5a, 5b, and 6c.
Files and variables
File: StealthyConfigs.zip
Description: This folder contains 4 ensembles of stealthy hyperuniform point patterns:
- PCCM01_1600_2D-box_RandU_Stealthy0.2_*.txt
- PCCM01_1600_2D-box_RandU_Stealthy0.4_*.txt
- PCCM01_1600_2D-box_RandU_Stealthy0.48_*.txt
- PCCM01_10000_2D-box_RandU_Stealthy0.48_*.txt
Where * denotes an integer starting at 0 and indexes a particular point configuration. Ensemble 1. contains 100 stealthy hyperuniform configurations with \chi = 0.2 and N = 1600 points, ensemble 2. contains 99 stealthy hyperuniform configurations with \chi = 0.4 and N = 1600 points, ensemble 3. contains 100 configurations stealthy hyperuniform configurations with \chi = 0.48 and N = 1600 points, and ensemble 4. contains 98 stealthy hyperuniform configurations with \chi = 0.48 and N = 10000 points.
Each file contains N rows, each corresponding to the position of a point in the configuration, and two columns corresponding to the x (first column) and y (second column) coordinates of each point.
Each configuration is in a square box, whose bottom left-hand corner is placed at the origin, of side length sqrt(N).
Code/software
The code used to generate the spatial tessellations of these point patterns and then to analyze the structures of those tessellations is available at: https://github.com/DMREF-networks/Network_Structure_Characterization.
