[GfImFreq] Matsubara Green’s function in imaginary frequencies

Reference

class triqs.gf.GfImFreq(**kw)[source]

Parameters (KEYWORD argument ONLY)

mesh: MeshImFreq, optional: The mesh of the Green function If not present, it will be constructed from the parameters beta, [n_points], [statistic]
data: numpy.array, optional: The data of the Gf. Must be of dimension mesh.rank + target_rank. Incompatible with target_shape
target_shape: list of int, optional: Shape of the target space. Incompatible with data
is_real: bool: Is the Green function real valued ? If true, and target_shape is set, the data will be real. No effect with the parameter data.
name: str: The name of the Green function. For plotting.

density(*args, **kwargs)

Compute the density matrix of the Greens function

Parameters:: beta (float, optional) – Used for finite temperature density calculation with MeshReFreq.
Returns:: density_matrix – Single particle density matrix with shape target_shape.
Return type:: ndarray

Notes

Only works for single mesh Greens functions with a, Matsubara, real-frequency, or Legendre mesh.

HDF5 data scheme

The GfImFreq (Format= “GfImFreq”) is decomposed in the following objects:

Name	Type	Meaning
Mesh	MeshGf	The mesh
Data	3d numpy of complex	Data[n,i1,i2] is the element of the Green function where: n is the Matsubara index i1, i2 are the indices For real GF in time, we store only starting from n=0 and the rest is deduced by symmetry
IndicesL,IndicesR	string	The Python repr of the indices, e.g. (1,2), or (1,) repr(this_string) reproduces the indices
Name	string	Name of the Green function block
Note	string	Note
