cisajscktalt.dat

This file is the outputted files for the two-body Green’s function \(\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}c_{k\sigma_3}^{\dagger}c_{l\sigma_4}\rangle\). The target components are set in the input file with the keyword “TwoBodyG”. An example of the file format is as follows.

File name

  • Lanczos method: ##_cisajscktalt.dat

  • TPQ method: ##_cisajscktalt_set??step%%.dat

  • TPQ/cTPQ method with OutputGreenFormat=1: ##_cisajscktalt_tpq.dat

  • Full diagonalization method, LOBCG method: ##_cisajscktalt_eigen&&.dat

  • Full diagonalization method, LOBCG method with OutputGreenFormat=1: ##_cisajscktalt_eigen.dat

  • Real time evolution method: ## cisajscktalt step%%.dat

  • Real time evolution method with OutputGreenFormat=1: ##_cisajscktalt_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

  • [int01]  [int02]  [int03]  [int04]  [int05]  [int06]  [int07]  [int08]  [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

  • [int01], [int03],[int05], [int07]

    Type : Int

    Description : The integer of the site number. [int01], [int03], [int05], and [int07] show the \(i\), \(j\), \(k\), and \(l\) site numbers, respectively.

  • [int02], [int04],[int06], [int08]

    Type : Int

    Description : The integer of the spin index:
    0: Up-spin
    1: Down-spin.
    [int02], [int04], [int06], and [int08] show \(\sigma_1\), \(\sigma_2\), \(\sigma_3\), and \(\sigma_4\), respectively.

  • [double01], [double02]

    Type : Double

    Description : The value of \(\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}c_{k\sigma_3}^{\dagger}c_{l\sigma_4}\rangle\).
    [double01] and [double02] show the real and imaginary part of \(\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}c_{k\sigma_3}^{\dagger}c_{l\sigma_4}\rangle\), respectively.
