Comment: The authors claims that they can explain the pseudogap phase using their simple theory. I see two problems: they have NO quantitative results, just assumptions, and second, if they only propose a mean-field theory. I hardly believe that a zero temperature theory can be extended at 300 K or 500 K in the pseudogap phase.
The most significant critic has been pointed out in this paper
http://arxiv.org/abs/cond-mat/0312385
Indeed, the authors seems to ignore the experimental phase diagram that has been obtained by many groups: there are two transitions lines in the pseudogap phase, one is T* the transition for the pseudogap itself, and the second one is the transition T' which is believe to be a vortex transition or the point where phases start to be correlated.
