Description
Summary:A spin-fermion and Landau–Ginzburg model for high-temperature superconductors are formulated
 and analyzed with unbiased numerical techniques. The study of the competition between
 d-wave superconductivity and antiferromagnetism in the clean limit suggests that the phase diagram
 is not universal. When chemical disorder is considered, a «clustered state» with short range
 order but without long range order appears leading to the possibility of a giant proximity effect.
 The influence of disorder on the spectral function is also addressed and results are compared to
 available angle resolved photoemission data for cuprates.
