triqs.operators.util

Utilities built on top of Operator.

Bundles the model Hamiltonians (triqs.operators.util.hamiltonians), common observables (triqs.operators.util.observables), Coulomb-tensor constructors (triqs.operators.util.U_matrix), block/index helpers (triqs.operators.util.op_struct) and coefficient extractors (triqs.operators.util.extractors).

Modules

U_matrix	Functions to construct Coulomb tensors.
extractors	Extract coefficients (matrices and tensors) from many-body operators.
hamiltonians	Standard local interaction Hamiltonians as Operator objects.
observables	Operators for commonly used observables.
op_struct	Block/index helpers for many-body operators and Green's functions.
