Datenpaket: Thermodynamic Stability at the Two-Particle Level - Numerical results for the two-orbital Hubbard model (beta = 35 two-particle functions, further additional results for U = 1.465, μ = 1.42)

This dataset contains a part of the DMFT/QMC results for the example of the two-orbital Hubbard model shown in the article "Thermodynamic Stability at the Two-Particle Level". It contains further additional statistically independent results (i.e. using multiple different PRNG seeds) for the two-particle Green's functions at inverse temperature beta = 35, Hubbard interaction parameter U = 1.465, and chemical potential μ = 1.42, calculated to assess the result quality. Other numerical results can be found in the main dataset listed under related identifiers and its other subdatasets.

All data files are zstd-compressed HDF5 output files as generated by w2dynamics for worm-sampling calculations of the two-particle Green's functions of the auxiliary impurity problem of two-orbital Hubbard models on a Bethe lattice with density-density interaction with fixed ratios between the interaction coefficients at inverse temperature beta = 35, Hubbard interaction parameter U = 1.465, and chemical potential μ = 1.42. The individual file names contain a PRNG seed index, e.g. 's11' for index 11 (with indices 1 and 2 to 10 found in one of the other datasets each). More detailed descriptions and instructions can be found in the included readme file or the technical remarks on the main dataset.
