The code and data for uncertainty quantification with multiple chiral two-nucleon interactions in symmetric nuclear matter

This research compendium contains the manuscript source, numerical inputs, reference outputs, figures, and Python code associated with the study of uncertainty quantification for symmetric nuclear matter calculated in the Brueckner-Hartree-Fock approximation with order-by-order chiral two-nucleon interactions. The analysis includes - single-interaction Gaussian-process truncation models- an equal-weight finite Gaussian-mixture baseline- a metadata-kernel multi-output Gaussian process for the common RKE-EMN ensemble- a nine-point sparse training grid with a ten-point sensitivity check- leave-one-interaction-out ensemble-coverage tests The scope is restricted to the two-nucleon sector. Three-nucleon forces and uncertainties from the many-body approximation are not included in the reported bands.
