ToTightbinding

ResponseFunction.ToTightbinding(G) transforms a response function object to a tight binding object that, when solved, has the response function $G$ as its one particle Green's function.

Depending on the representation used for the response function (Tridiagonal, Anderson, or Natural impurity orbitals) one finds a different layout of the tight binding Hamiltonian that it represents. Transformations between the different layouts are given by unitary basis transformations. In all cases the dimension of the sites, i.e. the number of quantum degrees of freedom per site such as spin-orbitals, is given by the BlockSize of the response function.
