These datasets were used to produce all figures in the linked arXiv paper. If you use them, please cite the paper.
We use the most popular data storage format hdf5 due to possibility of including metadata (unlike numpy), processing the data without loading the entire dataset into memory with a single command, and other features that make the workings with data easier.
Unless noted otherwise, datasets contain time evolutions for XXZ model with ZZ interaction strength Delta=1 and open boundary conditions. All arrays have time as the first column.
Example readout of a dataset is presented in the notebook example_dataset_readout.ipynb. It requires installation of some *.h5 processing library. In the example we use python and tables. For a quick glimpse what the datasets contain, on linux use vitables to explore the files and arrays therein.

Datasets not used in the paper but some people may find them useful. Here, disorder comes from quasiperiodic distribution W_i = W cos(2 \pi \zeta i + \phi) where i is the index of the lattice site, \zeta = (\sqrt(5) - 1)/2 is the golden ratio and \phi is random variable uniformly distributed in the interval [0, 2\pi].
TDVP_quasiperiodic_OBC.h5 Same as TDVP_XXZ_OBC.h5 above with L=[50, 100, 200] and bond dimensions chi=[128, 192]
ChebyshevPP_XXZ_quasiperiodic_OBC.h5 Same as other Chebyshev* datasets, with L=[14, 16] and W=[0.5, 1, 1.5, 2, 3, 4, 5].
