Observation of Perfect Absorption in Hyperfine Levels of Molecular Spins with Hermitian Subspaces

TITLE: Observation of Perfect Absorption in Hyperfine Levels of Molecular Spins with Hermitian Subspaces AUTHORS: Claudio Bonizzoni, Daniele Lamberto, Samuel Napoli, Simon Günzler, Dennis Rieger, Fabio Santanni, Alberto Ghirri, Wolfgang Wernsdorfer, Salvatore Savasta and Marco Affronte MAIL TO: claudio.bonizz[email protected] PAPER TO BE PUBLISHED ON: Nature Communications ZENODO LINK (THIS FOLDER): https://doi.org/10.5281/zenodo.17609672 ARXIV LINK: https://arxiv.org/abs/2505.05966v2 DATASET DESCRIPTION The data available in this folder correspond to the ones (experiments, fit and simulations) shown in Figures 1,2,3,4,5,6 of the main article described above. The data are given in tab delimited .txt format and are organized as follows. Each file name corresponds to the relevant figure panel according to the nomenclature “figureNUMBERpanel” (e.g. “figure1d”) and, when applicable, to the associated subpanel (“_upper” or “_lower”, e.g. “figure2d_lower”). For each dataset, the first row of every column contains the label describing the data (along with their units of measurements). For three-dimensional datasets (x, y, z), such as reflection spectra, the first two columns contain all the x and y coordinate pairs, while the third column contains the corresponding z values. For some data, the file name explicitly includes the term “_matrix” (e.g. “figure4b_matrix”). In these cases, to reduce the file size, the x and y axes are provided only once as vectors containing their unique values rather than as individual x–y pairs, while the z values are provided directly as a matrix. Note that the datasets associated with Figure 6 are provided as two separate files, one containing the experimental data (“_experim_data”) and the other containing the theoretical data (“_theoret_data”). The improve data portability all files are loaded in the Zenodo folder both as single files as well as a unique compressed .zip folder containing the whole dataset.
