The quantum impurity solvers will generate a lot of data files at run time. In this section, we will depict their formats and usages in detail.

The data files could be classified as the following kinds:

  • Direct output
    • [Terminal output] // Many useful stuffs in it
  • Green's function data
  • Hybridization function data
  • Self-energy function data
    • solver.sgm.dat // $\Sigma(i\omega_n)$
    • [solver.hub.dat] // $\Sigma_{\text{atomic}}(i\omega_n)$ and $G_{\text{atomic}}(i\omega_n)$
  • Two-particle Green's function data
    • [solver.twop.dat] // Two-particle Green's function and vertex function
    • [solver.vrtx.dat] // Two-particle Green's function and vertex function
    • [solver.pair.dat] // Pairing susceptibility
  • Susceptibility data
    • [solver.schi.dat] // Spin-spin correlation function in $\tau$ space
    • [solver.sfom.dat] // Spin-spin correlation function in Matsubara frequency space
    • [solver.ochi.dat] // Orbital-orbital correlation in $\tau$ space
    • [solver.ofom.dat] // Orbital-orbital correlation in Matsubara frequency space
  • Physical observables data
    • solver.hist.dat // Histogram for perturbation expansion order
    • solver.prob.dat // Atomic state probability
    • solver.nmat.dat // Occupation number
    • [solver.kmat.dat] // $\langle k \rangle$ and $\langle k^2 \rangle$
    • [solver.lmat.dat] // $\langle k_L \rangle$ and $\langle k_R \rangle$
  • Miscellaneous data
    • [solver.kernel.dat] // Frequency-dependent interaction
    • solver.status.dat // Status of the quantum impurity solvers
    • solver.diag.dat // Snapshot of the current configuration for diagrammatic perturbation expansion
