CalculateHybridizationFunction
Responsefunction.CalculateHybridizationFunction(G0,Sigma) calculates the interacting impurity bath Green's function. Given a lattice with local Green's function $G_0(\omega)$ and a local self energy $\Sigma(\omega)$. The full Green's function then is $G(\omega) = G_0(\omega-\Sigma(\omega))$. If we want to add a self energy on all sites, except for the site we are looking at we get $$G_{Bath} = \frac{1}{G_0(\omega-\Sigma(\omega))^{-1} - \Sigma(\omega)}$$. This Green's function can be used to define the hybridisation function of an Anderson impurity model representing a lattice.
