    • The t - j model, which is basically a large-U case of the Hubbard model, also leads to pairing, see e.g. O.P. Sushkov, Phys. Rev. B 54, 9988 (1996) and reference therein.

    • note
    • This does not imply that we are switching to a new representation with the vacuum at half filling; nor does it imply that the hole concentration or other parameters are necessarily the same as in hole or electron superconductors. The conventional nature of these statement is clear from the fact that when holes are paired, so are the electrons.

    • note
    • 4, just two W = 0 configurations contribute significantly at weak coupling, and thus effective interaction and binding energy are the same.
