This text file describes the contents of the Open Data submission associated with R. J. Needs, M. D. Towler, N. D. Drummond, P. Lopez Rios, and J. R. Trail, J. Chem. Phys. 152, 154106 (2020) (DOI:10.1063/1.5144288), containing the pertinent CASINO input/output files used to make figures and tables in the paper which do not appear in prior publications (references for these can be found in the manuscript, summarized under "other figures" below). Each figure and table has its own associated tarball .tar.gz (enclosed in .zip for technical reasons) containing a root directory named whose contents are described below. For information regarding files used and produced by CASINO, please refer to the user's manual distributed with CASINO. Where multiple "out*" files are present, these correspond to continuation runs; "out" is typically the output file from the last such run. Orbital and parameter files sometimes appear in the main directory and are soft-linked thoughout the directory structure. Description of contents ======================= Fig01_li_reblock ---------------- NOTE: Fig. 1 was produced with an old version of CASINO. Here we provide the files for a similar calculation using a current version of CASINO. Note that the results do not exactly match those in the plot. * 01_opt: directory containing the Jastrow factor optimization run. * 02_vmc: directory containing the VMC run, with the (large) vmc.hist file replaced with the output from the reblock utility in reblock.out. Fig02_c_cusp ------------ * nocusp, jcusp, ocusp: directories containing runs using a wave function without an e-n cusp, one in which the e-n cusp is enforced via the Jastrow factor, and one in which the e-n cusp in enforced by modifying the Gaussian orbitals, respectively. Each of these directories contains: - 01_opt: directory containing the Jastrow factor optimization run. - 02_plot: directory containing the CASINO run to plot the local energy as shown in the plot - see file casinoplot.dat. Fig03_heg_dmc ------------- NOTE: Fig. 3 was produced as a test a fair while ago, and the files for the excited state runs are missing from our records. * dmc_gs: directory containing the ground-state DMC run. Fig04_heg_popbias ----------------- * 54, 114, 246: directories containing runs at system sizes N=54, 114, and 246, respectively.

Fig05_heg_dtbias ---------------- * 54, 114, 246: directories containing runs at system sizes N=54, 114, and 246, respectively. Each of these directories contains: - j1, j2: directories containing runs using a simple Jastrow factor and a good Jastrow factor, respectively.

Fig07_si_jastrow ---------------- * 01_dtn, 02_dtn_aniso: directories containing runs using the two Jastrow factors discussed in the paper. Each of these directories contains: - 01_opt: directory containing the Jastrow factor optimization run. - 02_plot: directory containing the CASINO run to plot the Jastrow factor. File 2Dplot_*.dat contains the electron-electron-nucleus contibution to the Jastrow factor. * 2Dplot_diff.dat: file plotting the difference between the electron-electron-nucleus contributions to both Jastrow factors. Fig08_c2_mdet ------------- * 0010..5000: directory containing runs corresponding to using the indicated number of CSFs in the trial wave function. Each of these directories contains: - 01_gen_mdet: directory containing the CASINO run generating the intermediate mdet.casl file. - 02_compress: directory in which det_compress has been run, with det_compress.out containing its output. * results.txt: summary of the results shown in the plot.
