triqs_ctint.solver.Solver.solve

Solver.solve(**solve_params)

Solve the impurity problem.

Parameters:

solve_paramsdict {‘param’:value} that is passed to the core solver.

The only two required parameters are

• h_int: The local interaction Hamiltonian

• n_cycles: The number of Monte-Carlo cycles

For the other optional parameters see documentation. Note that in this Python Wrapper the alpha-tensor is optional. If not given, it will be constructed from the density matrix of the SC Hartree Fock solution.

deltafloat (default 0.1)

The value of the delta parameter used to construct the alpha tensor. The larger the value of delta, the better the Monte-Carlo sign, at the cost of a larger perturbation order. This parameter is only used if alpha is not given explicitly.
