triqs_xca.triqs_solver.TriqsSolver

class triqs_xca.triqs_solver.TriqsSolver(beta, gf_struct, eps, w_max, verbose=True)

TRIQS Sum-Of-Exponentials bold HYBridization expansion impurity solver (triqs_xca)

Parameters:

betadouble

inverse temperature

gf_structlist of pairs [ (str,int), …]

Structure of the Green’s functions. It must be a list of pairs, each containing the name of the Green’s function block as a string and the size of that block. For example: [ ('up', 3), ('down', 3) ].

epsdouble

Accuracy of the Discrete Lehmann Representation (DLR) imaginary time basis

w_maxdouble

Energy cut-off of the of the Discrete Lehmann Representation (DLR) imaginary time basis

verbosebool, optional

Verbose printouts (default: True)

Methods

solve(h_int, order[, compress_hybridization])

Self-consistent solution of the pseudo-particle Green's function and pseudo-particle self-energy.
