Initial file¶
This file contains the values of Green’s function
\(G_{ij\sigma_1\sigma_2}\equiv \langle c_{i\sigma_1}^\dagger c_{j\sigma_2}\rangle\)
to be read for an initial configuration.
The unspecified elements are assumed to be zero.
The file format is the same as that of the green output file.
An example of the file format is presented below.

Parameters¶
[i],[j]Type : Integer
Description : An integer giving a site index (\(0 \le i, j < {\rm Nsite}\)).
[s1],[s2]Type : Integer
Description : An integer giving a spin index: either 0 (up-spin) or 1 (down-spin).
[v.real],[v.imag]Type : Float
Description : Values for the real and imaginary parts of \(\langle c_{i\sigma_1}^{\dagger} c_{j\sigma_2}^{\phantom{\dagger}} \rangle\), respectively.
