pytriqs.gf.Gf¶

class pytriqs.gf.Gf(**kw)[source]¶

TRIQS Greens function container class

Parameters:

mesh (TRIQS Greens function mesh) – One of the meshes of the module ‘meshes’.
data (numpy.array, optional) – The data of the Greens function. Must be of dimension mesh.rank + target_rank.
target_shape (list of int, optional) – Shape of the target space.
is_real (bool) – Is the Greens function real valued? If true, and target_shape is set, the data will be real. Mutually exclusive with argument data.
indices (GfIndices or list of str or list of list of str, optional) – Optional string indices for the target space, to allow e.g. ['eg', 'eg']. list of list of str: the list of indices for each dimension. list of str: all indices are assumed to be the same for all dimensions.
name (str) – The name of the Greens function for plotting.

Notes

One of target_shape or data must be set, and the other must be None. If passing data and indices the data.shape needs to be compatible with the shape of indices.

conjugate()[source]¶

Conjugate of the Greens function.

Returns:	G – Conjugate of the Greens function.
Return type:	Gf (copy)

copy()[source]¶

Deep copy of the Greens function.

Returns:	G – Copy of self.
Return type:	Gf

copy_from(another)[source]¶: Copy the data of another Greens function into self.

data¶

ndarray – Raw data of the Greens function.

Storage convention is self.data[x,y,z, ..., n0,n1,n2] where x,y,z correspond to the mesh variables (the mesh) and n0, n1, n2 to the target_space.

density(*args, **kwargs)[source]¶

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`.

Notes

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

set_from_pade(*args, **kw)¶

Signature : (gf_view<refreq,matrix_valued> gw, gf_view<imfreq,matrix_valued> giw, int n_points = 100, float freq_offset = 0.0) -> None

target_rank¶: int – The rank of the target space.

target_shape¶: (int, …) – The shape of the target space.

total_density(*args, **kwargs)[source]¶

Compute total density.

Returns:	density – Total density of the Greens function.
Return type:	float

Notes

Only implemented for single mesh Greens function with a, Matsubara, real-frequency, or Legendre mesh.

transpose()[source]¶

Take the transpose of a matrix valued Greens function.

Returns:	G – The transpose of the Greens function.
Return type:	Gf (copy)

Notes

Only implemented for single mesh matrix valued Greens functions.

x_data_view(x_window=None, flatten_y=False)[source]¶

Helper method for getting a view of the data.

Parameters:	x_window (optional) – The window of x variable (omega/omega_n/t/tau) for which data is requested. flatten_y (bool, optional) – If the Greens function is of size (1, 1) flatten the array as a 1d array.
Returns:	(X, data) – X is a 1d numpy array of the x variable inside the window requested. data is a 3d numpy array of dim (:,:, len(X)), the corresponding slice of data. If flatten_y is True and dim is (1, 1, *) it returns a 1d numpy array.
Return type:	tuple

zero()[source]¶: Set all values to zero.
