Models de superconductivitat deduïts a partir de respostes dielèctriques

This research attempts to determine the hole-hole coupling mechanism which leads to the superconducting gap in the Fermi level. We shall consider different mechanisms having origine as a common ingredient, since all arise from the dielectric responses. These dielectric responses produce attractive interactions in a frequency interval and these interations allow by the strong coupling theory to obtain high Tc superconductivity.
