    • note
    • Superconductivity is only detectable as an instability of the Fermi liquid, the superconducting phase itself being characterized by an order parameter of higher order in 1/N. This makes it difficult to put superconducting and charge instabilities on equal footing in order to investigate their interplay.

    • A specific example of this effect can be given by a mean-field treatment of a Kondo-lattice model [21], which showed, indeed, the large stabilizing effect that superconductivity may have in providing a better alternative than phase separation to use the attraction present in the system.

    • note
    • These fluctuation effects are not present in our treatment: Our leading order large-N approach, having a diagrammatic structure very similar to RPA, shares many features of a mean-field approach.
