Standard output files
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
- solver.green.dat // $G(\tau)$
- solver.weiss.dat // $G_0(\tau)$
- solver.grn.dat // $G(i\omega_n)$
- solver.wss.dat // $G_0(i\omega_n)$
- Hybridization function data
- solver.hybri.dat // $\Delta(\tau)$
- solver.hyb.dat // $\Delta(i\omega_n)$
- 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
