A theoretical preprint presents a way to turn impedance and admittance responses into exact Hamiltonians and controlled reduced models for superconducting circuits. Its examples cover discrete filters, finite-band metamaterials, nonreciprocal waveguides and giant atoms, while stressing that the reductions depend on their approximation regimes.
