DynamicalGreen.dat¶
This file is the outputted file for calculating the dynamical Green’s function. An example of the file format is as follows.
File name¶
##_DynamicalGreen.dat
## indicates [string02] in a ModPara file.
When the finite-temperature eigenstate loop and the multiple-operator /
multiple-bra modes are enabled (SpectrumLoopExct, SpectrumNumOp,
SpectrumNumBra in the ModPara file), one file is
written per (eigenstate, ket operator, bra) combination and the
zero-based indices are appended to the file name:
##_DynamicalGreen_idx.dat — eigenstate idx (
SpectrumLoopExct).##_DynamicalGreen_idx_op.dat — eigenstate idx, ket operator set op (
SpectrumNumOp).##_DynamicalGreen_idx_op_bra.dat — eigenstate idx, ket operator set op, bra operator set bra (
SpectrumNumBra).
The file format described below is identical for all of these variants.
File format¶
Lines 1-: [double01] [double02] [double03] [double04]
Parameters¶
[double01], [double02]
Type : Double
Description : The value of the frequency \(z\).[double01] and [double02] are a real and an imaginary part of \(z\), respectively.[double03], [double04]
Type : Double
Description: The value of dynamical Green’s functions \(G(z)\).[double03] and [double04] are a real and an imaginary part of \(G(z)\), respectively.
