This dataset provides data files for the equation of state and equilibrium configurations of soft-disk models used in "Liquid-hexatic transition for soft disks" Physical Review E 108, 024103 (2023) by Yoshihiko Nishikawa, Werner Krauth, and A. C. Maggs. The following directories are included. - equation_of_state: This directory includes two CSV files for the equation of state plotted in the paper. - equilibrium_configuration: This directory includes equilibrium configurations of N = 1024^2 particles of the models studied in the paper. An equilibrium configuration is stored in start.h5, a HDF5 file, together with the parameters for the simulation. By using the CUDA code available at https://github.com/jellyfysh/SoftDisks, you can perform an equilibrium simulation starting from the configuration stored in start.h5.
