2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/19937An new superconducting hamiltonian is introduced for which the exact ground state is the Anderson resonating valence bond. It differs from the t-J and hubbard hamiltonians in possessing a powerful attractive force. Its superconducting state is characterized by a full and intact d-wave tunneling gap, quasiparticle photoemission intensities that are strongly suppressed, a suppressed superfluid density, and an incipient Mott-Hubbard gap.4 pages of REVTeX, no figuresSuperconductivitytext
