Datasets to produce figures of the manuscript "Quantum Critical Points and the Sign Problem" Contents: All figures are divided by folders, Main_text (Figs. 1 to 4) and Supplemental Material (Figs. S1 to S11). In each folder the data files (.dat) and scripts (.py) that generate the figures are included. Data files have easily readable names, with relevant parameters explicitly given. Using Python 3+ with an updated Matplotlib can directly reproduce the figures in the manuscript. We further include the Figures (.pdf or .png) in the corresponding folders for convenience. Data can be reproduced using the QUEST: QUantum Electron Simulation Toolbox, freely available at https://www.cs.ucdavis.edu/~bai/QUEST_public/ The geometry files (.geom) and example input files (.in) for the two types of lattices used are given in this repository.
