AnomalousG.dat

This file is the output file for anomalous pair Green’s functions specified by the input file with the keyword AnomalousG. A line with type 0 is the expectation value of \(c_{i\sigma_1}c_{j\sigma_2}\), and a line with type 1 is the expectation value of \(c_{i\sigma_1}^{\dagger}c_{j\sigma_2}^{\dagger}\). An example of the file format is as follows.

0 0 0 0 1 -0.5000000000 0.0000000000
1 0 1 0 0 -0.5000000000 0.0000000000

File name

  • Lanczos method, LOBCG method: ##_AnomalousG.dat

  • TPQ method, cTPQ method: ##_AnomalousG_set??step%%.dat

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

  • Full diagonalization method: ##_AnomalousG_eigen&&.dat

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

  • Real time evolution method: ##_AnomalousG_step%%.dat

  • Real time evolution method with OutputGreenFormat=1: ##_AnomalousG_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 or time evolution 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] [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]

    Type : Int

    Description : The anomalous pair type:
    0: \(\langle c_{i\sigma_1}c_{j\sigma_2}\rangle\)
    1: \(\langle c_{i\sigma_1}^{\dagger}c_{j\sigma_2}^{\dagger}\rangle\).

  • [int02], [int04]

    Type : Int

    Description : The integer of the site number. [int02] and [int04] show the \(i\) and \(j\) site numbers, respectively.

  • [int03], [int05]

    Type : Int

    Description : The integer of the spin index:
    0: Up-spin
    1: Down-spin.
    [int03] and [int05] show \(\sigma_1\) and \(\sigma_2\), respectively.

  • [double01], [double02]

    Type : Double

    Description : The value of the anomalous pair Green’s function.
    [double01] and [double02] show the real and imaginary parts, respectively.
