Query: Superconductivity in the "Hot Spots" Model of the Pseudogap State:
  Impurity Scattering and Phase Diagram   We analyze the anomalies of superconducting state (both s- and d-wave
pairing) in the model of the pseudogap state induced by Heisenberg spin
fluctuations of antiferromagnetic short-range order, and based on the scenario
of strong scattering near the "hot spots" on the Fermi surface. We present
microscopic derivation of Ginzburg-Landau expansion, taking into account all
Feynman graphs of perturbation theory for electron interaction with
fluctuations of short-range order and in the "ladder" approximation for
electron scattering by normal (nonmagnetic) impurities. We determine the
dependence of superconducting critical temperature T_c and other
characteristics of a superconductor on the parameters of the pseudogap and
impurity scattering. It is shown that within this model it is possible to
explain the typical phase diagram of high- temperature superconductors.
