Phys. Rev. B 60, 14585–14588 (1999)Spin-fluctuation exchange study of superconductivity in two- and three-dimensional single-band Hubbard modelsReceived 24 June 1999; published in the issue dated 1 December 1999 In order to identify the most favorable situation for superconductivity in the repulsive single-band Hubbard model, we have studied instabilities for d-wave pairing mediated by antiferromagnetic spin fluctuations and p-wave pairing mediated by ferromagnetic fluctuations with the fluctuation exchange approximation in both two dimensions and three dimensions. By systematically varying the band filling and band structure we have shown that (i) d pairing is stronger in two dimensions than in three dimensions and (ii) p pairing is much weaker than d pairing. © 1999 The American Physical Society URL:
