mf as a Mott pseudogap since it arises from correlation effects in the spirit of the Mott-Hubbard metal-insulator transition. We do not address disorder related localization effects away from half filling.

There are many other views on the origin of pseudogap in the cuprates (superconducting fluctuations, etc.). See, e. g., R.S. Markiewicz, cond-mat/0108075, Phys. Rev. Lett. (to be published); S. Andergassen et al., Phys. Rev. Lett. 87, 056401 (2001).

Optimal values of t′, t″ differ slightly in t-U and t-J models [Tohyama et al., J. Phys. Soc. Jpn. 69, 9 (2000)], former values are more relevant here.

Note that in the t-J models the bands are inverted for treating electron doping, leading to a sign change of t' which is not needed in the t-U models.
