This data repository contains the original figures, numerical data, and plot scripts to reproduce the figures from the publication "Effective enhancement of the electron-phonon coupling driven by nonperturbative electronic density fluctuations" in the Physical Review Letters journal of the American Physical Society. LaTeX source files of the preprint can be found on the corresponding arXiv page.

The raw DMFT results were produced with the code package w2dynamics. For the subsequent postprocessing the "w2dyn_post" script of the open-source package correl was used. The numerical results are stored in the .npz, .pkl and .dat files of this repository: - b55.75_chi_q_3d.npz contains the data for Fig. 1 of the main text - diagrams.npz contains the numerical data for Fig. 3 of the main text - b55.75_hole_doping_data.npz contains the data for Fig. 2 of the main text and Figs. S2-S8 of the supplementary material - dif_bub_data.dat contains supplementary data for Fig. S3 of the supplementary material To access and plot the above data, the jupyter notebook "eph_plots.ipynb" can be used, which creates all plots of the main text and supplemental material and stores them in the "plots" directory. There, Figs. 3 and S1 can also be found as these are not created by the notebook. Lastly, to run the notebook, we recommend using a conda environment. The "eph.yml" file contains all relevant packages with the specific versions used in this publication. The conda environment can be set up by simply running the following command:

$ conda env create -f eph.yml
