Description
We propose a general scheme to probe the compatibility of arbitrary pairing states with a given normal state Hamiltonian by the introduction of a concept called "superconducting fitness". This quantity gives a direct measure of the suppression of the superconducting critical temperature in the presence of key symmetry-breaking fields, even in complex multi-band systems. In the light of this new concept we analyze the multiband superconductor Sr2RuO4 and propose a new mechanism for the suppression of superconductivity, which we call inter-orbital effect, as a possible explanation for the unusual limiting feature observed in the upper critical field in this system.
