Data for "Thermodynamic bound on the Fano factor of a coherent thermoelectric heat engine".

Numerical data for the figures of the paper “Thermodynamic uncertainty relation of a coherent thermoelectric heat engine”. The dataset contains the numerical and analytical data used to produce the figures of the paper, including sampled thermodynamic-uncertainty-relation point clouds, Fano-factor bounds, heat-engine efficiency bounds, operating-sector diagrams, and charge-current precision comparisons for coherent thermoelectric transport. The calculations are based on Landauer–Büttiker scattering theory for two-terminal coherent conductors with arbitrary transmission functions, considering fermionic, bosonic, and classical carriers. The dataset includes random boxcar-transmission scans used to test the tightness of heat-engine-specific bounds. The repository includes the data used to produce Figures 2 and 3 of the main text and Supplementary Figures S1–S3. The data are provided as compressed NumPy archives (.npz), CSV files, JSON metadata, and figure-specific README files. The stored files include both raw numerical arrays and the processed quantities directly shown in the published figures, together with the corresponding parameters, and units.
