Data for the work "Efficient optimization of variational tensor-network approach to three-dimensional statistical systems"

This dataset contains the data supporting the work “Efficient optimization of variational tensor-network approach to three-dimensional statistical systems”.The structure of the dataset is:-Directory “Accuracy_and_efficiency_benchmark” contains the raw data for accuracy and efficiency benchmark of the split-CTMRG method (Fig. 8 in the paper).-Directory “Physical_quantity_for_3D_Ising_Model” contains the raw data for the magnetization, internal energy and specific heat of 3D Ising model calculated with split/reduced method (Fig. 9 and 10 in the paper).-A Jupyter notebook file “Data_readout_example.ipynb” shows how to read out and use the data. The function supporting the plot of Monte Carlo reference curve in the paper is also contained in this file.
