triqs_dft_tools.sumk_dft.SumkDFT.analyse_block_structure_from_gf
- SumkDFT.analyse_block_structure_from_gf(G, threshold=1e-05, include_shells=None, analyse_deg_shells=True)[source]
Determines the block structure of local Green’s functions by analysing the structure of the corresponding non-interacting Green’s function. The resulting block structures for correlated shells are stored in the
SumkDFT.block_structureattribute.This is a safer alternative to analyse_block_structure, because the full non-interacting Green’s function is taken into account and not just the density matrix and Hloc.
- Parameters:
- Glist of BlockGf of GfImFreq, GfImTime, GfReFreq or GfReTime
the non-interacting Green’s function for each inequivalent correlated shell
- thresholdreal, optional
If the difference between matrix elements is below threshold, they are considered to be equal.
- include_shellslist of integers, optional
List of inequivalent shells to be analysed. If include_shells is not provided all inequivalent shells will be analysed.
- analyse_deg_shellsbool
Whether to call the analyse_deg_shells function after having finished the block structure analysis
- Returns:
- Glist of BlockGf of GfImFreq or GfImTime
the Green’s function transformed into the new block structure
