This resource provides the Python scripts needed to generate the illustrations of quantum dynamics of excitons and phonons on a chain as shown in figures 3-6 of the manuscript published as arXiv:2302.03725 by J. Riedel, P. Gelß, R. Klein, and B. Schmidt. Note that the Python scripts build on our open-source WaveTrain software package for quantum dynamics which in turn builds on the scikit_TT software package for tensor trains. Both of them are freely available via the GitHub platform.
