Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | 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. |
