green¶
The one-body Green’s function
\(\langle c_{i\sigma_1}^{\dagger} c_{j\sigma_2}^{\phantom{\dagger}} \rangle\)
obtained by the UHF calculation is to be exported.
The indices of the component to be written are specified by OneBodyG.
The filename is associated with a keyword green in file.output section of the input parameter file.
An example of the output is presented below.
