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
