Data for work "Variationally optimizing infinite projected entangled-pair states at large bond dimensions: A split-CTMRG approach"

In this repository the raw data for the work "Variationally optimizing infinite projected entangled-pair states at large bond dimensions: A split-CTMRG approach" are provided. The work is available as preprint on arXiv: https://arxiv.org/abs/2502.10298 The data is either stored as raw text, the numpy file format or HDF5 generated by the variPEPS Python libary [1-3]. Structure: - In the folder plot_data/ the raw data used in the figures of the work are provided. These data have been generated from the files in the other folders. - In the folder energy_comparison/ the data used to generate the energy comparision at fixed chi_I = chi_E are available. - In the folder interlayer_chi_benchmark/ the data used to generate the energy comparision for a fixed chi_E=130 but different chi_I are provided. - In the folder scaling/ the data for the scaling analysis are available. - In the folder optimization_run/ the data for the variational optimization run with the split and conventional CTMRG method are provided.
