    • In diagrammatic language, this is equivalent to summing a class of diagrams to infinite order with intermediate states of any of the retained states in the Hilbert space.

    • Note that any Hamiltonian, including a Hamiltonian describing a many-body problem such as this one, is formally identical to that of a single-particle tight-binding model. The tight-binding model will not, however, generally be on a periodic lattice.

    • There are no frustrated loops in the single hole tight-binding model at this level.

    • The full bandwidth, which is twice as wide as that plotted for two holes in Fig. 7, should be used to calculate mstar .

    • This prescription is seen to be correct by numerically solving for the eigenstates of two electrons in an empty lattice. The correct angular momentum is obtained by counting zero crossings only after a gauge transformation is performed.

    • Note that < σ vec1 cdot σ vec2 > can become as small as -3 if the spins on sites 1 and 2 form a singlet.
