    • The reference spin state need not be the ground state of any frustrated Heisenberg antiferromagnet, but should have spin correlation similar to those of the superconductor one wishes to study.

    • For the nearest-neighbor spin-1/2 antiferromagnet on a square lattice, scrNijapprox 1.16. This is an appreciable fraction of the maximum value 2, because the short-range correlations of even a Néel-ordered antiferromagnet are well described in terms of a fluid of short valence bonds.

    • For example, pair-hopping terms are also obtained in the canonical transformation which eliminates doubly occupied sites from the problem. These are of order J and can easily be included. Our use of an effective pair Hamiltonian amounts to an instantaneous approximation for the two-particle vertex.
