Abstract
We show that for superconducting Sr2RuO4 any unconventional pairing in the part of the Fermi surface with Ru 4dxy orbital character is weakly coupled to that with Ru {4dxz,4dyz} orbital character. This naturally gives rise to two disparate energy scales in the superconducting state which leads to novel low temperature properties in a variety of thermodynamic and transport properties and which would also account for the large residual density of states seen in specific heat and nuclear quadrapole resonance measurements.
