    • We consider only cases where the ground state of the system is a flux lattice; other states are possible [12].

    • note
    • We have shown only that a hexagonal lattice leads to a local energy minimum for our final effective action, Eq. (6); the global minimum could have a different structure. The number and type of Goldstone modes would be the same, but the detailed form of the elastic energy would be different for a nonhexagonal lattice. See also Ref. [11].

    • note
    • It is easy to verify that keeping terms of higher than quartic power in either order parameter in Eqs. (2) does not affect our conclusions.

    • note
    • In conventional ferromagnets, the fluctuating vector potential leads to the dipole-dipole interaction. This is usually ignored for studying critical phenomena, despite its formal renormalization-group (RG) relevance, since it is very small compared to the exchange coupling. For the properties of a ferromagnetic superconductor, however, the coupling of the vector potential to the magnetization is crucial, as we will see.

    • We consider only magnetic states which are rotationally invariant in the plane perpendicular to the direction of the spontaneous magnetization.

    • note
    • To compare with Ref. [15], notice that these authors localized the potential in the second term and omitted both the last term and the subtraction leading to a instead of a in the next-to-last term. These approximations do not affect the leading elastic properties of the vortex-lattice.

    • Note that this is the so-called left strain tensor, as opposed to the more commonly used right strain tensor [23]. A discussion of why the left strain tensor is appropriate for the situation at hand can be found in Ref. [24].

    • note
    • 2 is less suitable for our purposes since it it has a strong intrinsic spin anisotropy [4], and the same is true for URhGe.
