Fit an imaginary-time Green’s function with a Discrete Lehmann Representation.
Applies to every overload. The input lives on a single imaginary-time mesh or on a product mesh pairing an imaginary-time axis with a lattice axis. Block and block-of-block Green’s function containers are handled component-wise, and product meshes are handled axis-wise. All target ranks (scalar, vector, matrix, rank-3, rank-4) are supported. The DLR grid is either specified by the spectral cutoff
w_maxand the toleranceeps, or passed directly as a DLR meshdlr_mesh.- Parameters:
- gGf[MeshImTime, 0]
The imaginary-time Green’s function to fit.
- w_maxfloat
Maximum real frequency captured by the DLR basis.
- epsfloat
Target accuracy of the DLR representation.
- symmetrizebool
If true, the DLR grid is symmetric about zero frequency.
- dlr_mesh
The DLR coefficient mesh to fit onto.
- Returns:
- Gf[MeshDLR, 0]
A Green’s function on the DLR coefficient mesh.
