Data for "Spectral and transmission properties of multiple correlated quantum dots made simple"

Numerical data and code for the paper "Spectral and transmission properties of multiple correlated quantum dots made simple". The dataset contains local spectral functions, transmission spectral functions, self-consistent occupations, and benchmark comparisons for multiple correlated quantum-dot systems. The calculations are based on steady-state density functional theory in the ideal STM limit, using exchange-correlation functionals designed for interacting multi-dot systems, and are compared with grand-canonical Lehmann calculations, with digitized numerical renormalization group (NRG) data, and with NRG calculations performed for this work. The folder data/ contains the data used to produce Figures 1–4, provided as compressed NumPy archives (.npz), CSV files, JSON metadata, and figure-specific README files, together with each figure as a PDF and a short Python script that redraws it from the stored data. The stored data include both raw numerical arrays and the rescaled quantities directly used in the published figures, together with the corresponding parameters, units, grid definitions, and array-orientation conventions. The folder nrg_benchmark/ contains the Python NRG code used for the Kondo-regime double and triple quantum dots of Figure 3, together with the input parameters, the configuration of the cluster runs, a validation test against exact diagonalization, and the resulting spectral functions and occupations. Changes in version 2: (i) added nrg_benchmark/; (ii) Figure 3 data updated to the revised figure: NRG curves for M = 2 and 3 added, and the gamma_off metadata entry corrected to 0; (iii) figure PDFs and plotting scripts added to each figure folder. Figures 1 and 2 are unchanged.
