Read this article?: nice article
Comment: My main problem concerning this article is about the existence of the first-order transition. Since it is well-known that first order transitions may reveal the failure of self-consistent or mean-field approaches. One can doubt about the fact that the pairing transition is first order since DMFT is a mean-field theory. It would nice to have a confirmation of simulations or other methods. Maybe someone could mention some references in the forum section.
