The effect of nonmagnetic disorder in the superconducting energy gap of strontium ruthenate

Abstract

We have performed for the strontium ruthenate compound, a disordered tight-binding numerical study in the unitary and intermedia scattering regimes analyzing the imaginary part of the self-consistent elastic scattering cross-section at zero temperature as a function of the superconducting gap parameter using the anisotropic limit of the γ sheet. We start this research, mentioning a set of different zero energy superconducting spectrum values inferred from experimental data. Furthermore, it is reproduced the Miyake–Narikiyo tiny triplet gap by varying the zero energy superconducting microscopic parameter. Additionally, using the finite temperature Matsubara Green functions formalism, it is investigated the energy gap as a function temperature and disorder. We conclude that the evolution of the reduced phase space using the elastic scattering cross-section for a triplet order parameter is a useful numerical technique and predicts the two elastic scattering regimes for strontium ruthenate.
