----------

This file is the outputted files for one-body Green’s function
:math:`\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}\rangle`. The target
components are set in the input file with the keyword “OneBodyG". An
example of the file format is as follows.

File name
~~~~~~~~~

*  Lanczos method: ##_cisajs.dat

*  TPQ method: ##_cisajs_set??step%%.dat

*  TPQ/cTPQ method with ``OutputGreenFormat=1``: ##_cisajs_tpq.dat

*  Full diagonalization method, LOBCG method: ##_cisajs_eigen&&.dat.

*  Full diagonalization method, LOBCG method with ``OutputGreenFormat=1``:
   ##_cisajs_eigen.dat.

*  Real time evolution method: ## cisajs step%%.dat

*  Real time evolution method with ``OutputGreenFormat=1``:
   ##_cisajs_te.dat

##, ??, %%, and && indicate [string02] in a ModPara file, the number of
runs in calculation in the TPQ method, the number of steps in the TPQ
method, and the index of the eigenvalues, respectively. In aggregate
files, each data row has leading index columns: ``set step`` for
TPQ/cTPQ, ``step`` for real-time evolution, and ``eigen`` for Full
diagonalization/LOBCG.

.. _file_format_40:

File format
~~~~~~~~~~~

*  [int01]  [int02]  [int03]  [int04]  [double01]  [double02]

For aggregate files generated with ``OutputGreenFormat=1``, the same
columns are preceded by ``set step``, ``step``, or ``eigen`` according to
the calculation method.

.. _parameters_40:

Parameters
~~~~~~~~~~

*  [int01], [int03]

   **Type :** Int

   **Description :** The integer of the site number.
   [int01] and [int03] show the
   :math:`i` and :math:`j` site numbers, respectively.

*  [int02], [int04]

   **Type :** Int

   | **Description :** The integer of the spin index.
   | [int02] and [int04] show
     :math:`\sigma_1` and :math:`\sigma_2`, respectively.
   | For Hubbard/Kondo systems:
   | 0: Up-spin
   | 1: Down-spin.
   | For SpinlessFermion/SpinlessFermionGC:
   | only 0 is output.

*  [double01], [double02]

   **Type :** Double

   | **Description :** The value of
     :math:`\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}\rangle`.
   | [double01] and [double02]
     show the real and imaginary part of
     :math:`\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}\rangle`,
     respectively.
