Abstract

I solved the Eliashberg equations for a multiband non-phononic s wave spin-glass superconductor, calculating the temperature dependence of the gaps and of superfluid density. Their behaviors were revealed to be unusual: showing non-monotonic temperature dependence and reentrant superconductivity. By considering particular input parameters values that could describe the iron pnictide EuFe2(As1-xPx)2, a rich and complex phase diagram arises, with two different ranges of temperature in which superconductivity appears.
