    • Any operator Q can be decomposed in a Hermitian and an anti-Hermitian part, Q= (A+iB) /2 where A= A† and B= B† are Hermitian operators (A≡Q+ Q†, iB≡Q- Q†). Because the complex conjugate of Eq. 4 must also be satisfied, A and B must satisfy similar conditions, □Ψ| A |Ψ□ = □ Ψ0 | A | Ψ0 □ and □Ψ| B |Ψ□ = □ Ψ0 | B | Ψ0 □.

    • In ab initio calculations like those of Refs., the equation of continuity 9 has to be imposed not only for a cluster of certain size (N), but also on a spatial grid containing a finite number of points { xl } l=1 Ng, and Ng should also be sufficiently large to ensure convergence.

    • In fact, it is easy to understand that this result is not limited to the linear response approximation: it is just the exact ground state |G□ of H+W, which minimizes E of Eq. 1. Being an eigenstate, there is no need to impose the equation of continuity. The latter is automatically satisfied in the state |G□, J= Jq, but this ground state cannot sustain a finite current, i.e., J=0. One should remark in this context that the assumption that all the model parameters of the Hamiltonian are real (which allows to consider that all the eigenstates are real) excludes superconductivity: the average of the current operator jq of Eq. 8 vanishes for any real state.
