4.2.18. SpectrumVec File

The header of the input file for the initial vector to calculate the dynamical Green’s functions is defined. The file name and the file format (binary type) are as follows.

File name

• ##_rank_$$.dat

## is the name of the head indicated by the key word SpectrumVec in the CalcMod file, and $$ is the number of the rank.

File format

• Line 1: [int01]

• Line 2: [int02]

• Lines 3 -: [double01]  [double02].

Parameters

• [int01]

  Type : Int

  Description : The total number of the targets of the Hilbert spaces.

• [int02]

  Type : Int

  Description : The number of Lanczos or TPQ steps.

• [double01], [double02]

  Type : double

  Description : The coefficient value of the input vector.

  [double01] is a real part and [double02] is an imaginary part.
