Kibble-Zurek Scaling and Spatial Statistics in Quenched Binary Bose Superfluids data

Numerical data of "Kibble-Zurek Scaling and Spatial Statistics in Quenched Binary Bose Superfluids". Communications Physics 9, 189 (2026) arXiv:2510.12770 (Preprint) Simulation data are from stochastic projected Gross-Pitaevskii equation (SPGPE) simulation. Dataset Structure The "number_evolution" folder contains data for condensate norm evolution for the miscible phase in the subfolder "miscible_total_atoms_vs_time" and for the immiscible phase in subfolder "immiscible_total_atoms_vs_time" from the simulation with different quench times. It also contains data for the equlibration time as a function of quench time for both the phases and norm evolution figure. The "domain_scaling" folder includes domain number and mean domain area as a function of quench time in the file named "domain_data_tauQs.txt" and related figure. Simulation data from SPGPE are stored in the subfolder "domain_at_equilibration_time" for the number of domains and mean domain area at equilibration time for different quench times starting from "tau10 to tau1000". All the simulation data for different quench times are based on 100 different noise realizations. All the tau* files inside "domain_at_equilibration_time" folder contain "Fortran" generated output data files. In each fort.* file, Column 1 contains the x-grid, Column 2 the y-grid, Column 3 the density of component 1, Column 4 the density of component 2, Column 5 the phase of component 1, and Column 6 the phase of component 2. The "vortex_scaling" folder includes vortex number as a function of quench time in the file named "vortex_number_tauQs.txt" and related figure. Simulation data from SPGPE are stored in the subfolder "vortex_at_equilibration_time" for the number of vortices at equilibration time for different quench times ranging from "tau10" to "tau1000". All the simulation data for different quench times are from 100 different noise realizations. All the tau* files inside "vortex_at_equilibration_time" folder contains "Fortran" generated output data files. In each fort.* file, Column 1 contains the x-grid, Column 2 the y-grid, Column 3 the density of component 1, Column 4 the density of component 2, Column 5 the phase of component 1, and Column 6 the phase of component 2. The "spatial_statistics" folder contains numerical analysis data for vortex statistics and domain (mean_positions) statistics, stored in "vortex_statistics" and "domain_statistics" subfolders, respectively. "vortex_statistics" contains 5 different subfolders: two for pairwise statistics, two for spacing statistics for the two condensate components, and one for numerical data. Each subfolder includes the corresponding figures for the spatial statistics split into different species. Same structure for "domain_statistics". The "wall_length_scaling" folder contains numerical analysis data for total domain wall length as a function of simulation time for different quench times. This includes data for wall length vs time for both the condensate components in the files named "wall_lengths_species1_tau*.txt" for component 1 and "wall_lengths_species2_tau*.txt" for component 2. tau* corresponding to different quench times ranging from 10 to 1000. All the data are averaged over 100 noise realizations.本数据集对应论文《淬火二元玻色超流体中的基布尔-祖雷克标度与空间统计》（Kibble-Zurek Scaling and Spatial Statistics in Quenched Binary Bose Superfluids），已发表于《通信物理学》（Communications Physics）9卷第189页（2026年），预印本编号arXiv:2510.12770。 本数据集的所有模拟数据均基于随机投影Gross-Pitaevskii方程（stochastic projected Gross-Pitaevskii equation, SPGPE）生成。 ## 数据集目录结构 1.
