This repository contains data for 

"Eigenstate Correlations in Dual-Unitary Quantum Circuits: Partial Spectral Form Factor",Felix Fritzsch, Maximilian F. I. Kieler, and Arnd Bäcker, arXiv:2407.19929 (2024);accepted for publication in Quantum,DOI: https://doi.org/10.48550/arXiv.2407.19929

DU_PSFF_archive.zip contains:

README.txt : the information below

Figures:  3 figures as used in the published article

Data: Data sets used for the creation of the figures,          stored as .npz archive, for documentation see          https://numpy.org/doc/2.2/reference/generated/numpy.savez.html

Notebooks:    Jupyter notebooks for:                      1) Loading the above data and plotting them using matplotlib                         (note, that this does not reproduce the plots of the published article,                          the later are generated with pyx, see https://pyx-project.org/)                      2) Computing the PSFF in the thermodynamic limit                      3) Computing the PSFF for finite system size                         (the latter two are cleaned up and simpliefied versions of the code used                          to produce the data for the publication)
