triqs_dft_tools.block_structure.BlockStructure.create_gf

BlockStructure.create_gf(ish=0, gf_function=<class 'triqs.gf.gf.Gf'>, space='solver', **kwargs)

Create a zero BlockGf having the correct structure.

For space='solver', the structure is according to gf_struct_solver, else according to gf_struct_sumk.

Default constructor is Gf which needs a mesh to be provided along. When using GfImFreq as gf_function, you have to supply at least beta as keyword argument.

Parameters:

ishint

shell index If space='solver', the index of the of the inequivalent correlated shell, if space='sumk', the index of the correlated shell

gf_functionconstructor

function used to construct the Gf objects constituting the individual blocks; default: Gf

space‘solver’ or ‘sumk’

which space the structure should correspond to

**kwargs

options passed on to the Gf constructor for the individual blocks
