    • While the Kondo-lattice model, Eq. 1, contains the physics of the indirect RKKY interaction between local moments, it is convenient for the theoretical discussion to introduce an (additional) explicit intermoment interaction.

    • In principle, the FL phase can be unstable to superconductivity at very low temperatures. We shall ignore this here, i.e., we work at low temperatures above the superconducting Tc.

    • The main effects of collinear itinerant antiferromagnetism are the breaking of SU (2) symmetry, band backfolding, and the opening of band gaps at the boundary of the antiferromagnetic Brillouin zone. These are correctly described in the standard saddle-point treatment, where order is implemented via a staggered mean field. Fluctuation effects, like collective modes of the ordered state, are not captured. However, those are unimportant for our discussion of adiabatic continuity.

    • If a combination of translation plus spin rotation is still a symmetry of the state, then a simple band structure arises even in the incommensurate case. However, often such a symmetry does not exist, e.g., due to spin-orbit interactions. For a discussion see, EULEEJ 0295-5075 10.1209/epl/i2004-10174-9
