Abstract

The unusual superconducting state in Sr₂RuO₄ has long been viewed as being analogous to a superfluid state in liquid ³He. Nevertheless, calculations based on this odd-parity state are presently unable to completely reconcile the properties of Sr₂RuO₄. Using a self-consistent quantum many-body scheme that employs realistic parameters, we are able to model several signature properties of the normal and superconducting states of Sr₂RuO₄. We find that the dominant component of the model superconducting state is of even parity and closely related to superconducting state for the high-T_c cuprates although a smaller odd-parity component is induced by spin-orbit coupling. This mixed pairing state gives a more complete representation of the complex phenomena measured in Sr₂RuO₄.
