Datasets for Figures in the Paper "Variational hydrodynamics of the classical Yukawa one-component plasma"

Data Structure

Each folder corresponds to an individual figure in the paper.
Below, we describe the contents and structure of each folder.

Folder "Figure_1":
-- All filenames follow the format "Omega_GammaOverGammaMelting_X_Kappa_Y.txt", where X is the value of Gamma over Gamma at melting for a specific kappa value, and Y is the corresponding kappa value.

...

Each file contains two columns: 1. normalized wavenumber 'q', 2. frequency normalized with respect to the plasma frequency.

Folder "Figure_2":
Each file contains two columns: 1. Gamma value, 2. normalized longitudinal speed of sound.
-- Files named "speed_of_sound_kappa_X.txt" contain results from our variational principle, and X denotes a specific kappa value.
-- Files named "MD_kappa_X.csv" contain digitized data from the molecular dynamics simulations published in: G. Silvestri, G. J. Kalman, Z. Donkó, P. Hartmann, M. Rosenberg, K. I. Golden, and S. Kyrkos, "Sound speed in Yukawa one-component plasmas across coupling regimes," Phys. Rev. E 100, 063206 (2019), and X denotes a specific kappa value.
-- Files named "speed_of_sound_QLCA_kappa_X.txt" contain results from QLCA, and X denotes a specific kappa value.
-- Files named "speed_of_sound_EQLCA_kappa_X.txt" contain results from the extended QLCA, and X denotes a specific kappa value.
-- Files named "speed_of_sound_EulerMF_kappa_X.txt" contain results from the Euler hydrodynamics + mean field approach, and X denotes a specific kappa value.

Folders "Figure_3" and "Figure_4":
-- Files named "MD_kappa_X_gamma_Y.txt" contain our molecular dynamics results for the dynamic structure factor, and X denotes the kappa value, and Y denotes the Gamma value.
Each file contains four columns: 1. normalized wavenumber 'q', 2. frequency normalized with respect to the plasma frequency, 3. dynamic structure factor S(q, w/w_p), 4. error for the dynamic structure factor.

The following files contain two columns: 1. normalized wavenumber 'q', 2. frequency normalized with respect to the plasma frequency.
-- Files named "Gamma_X_Kappa_Y.txt" contain results from our variational principle, and X denotes the Gamma value and Y denotes the kappa value.
-- Files named "QLCA_Gamma_X_Kappa_Y.txt" contain results from QLCA, and X denotes the Gamma value and Y denotes the kappa value.
-- Files named "EQLCA_Gamma_X_Kappa_Y.txt" contain results from the extended QLCA, and X denotes the Gamma value and Y denotes the kappa value.
-- Files named "EulerMF_Gamma_X_Kappa_Y.txt" contain results from the Euler hydrodynamics + mean field approach, and X denotes the Gamma value and Y denotes the kappa value.
