Understanding the superconducting Sr₂RuO₄ through Sr₂MoO₄

Sr₂RuO₄ is widely conceived to be a candidate chiral p-wave superconductor. Various aspects of its unconventional pairing have been and are still being actively studied. By contrast, its nonsuperconducting iso-structural and iso-electronic analog, Sr₂MoO₄, has received far less attention. In the hope of obtaining deeper insight about the superconductivity in Sr₂RuO₄, we present a comparative study of Sr₂RuO₄ and Sr₂MoO₄, focusing on their electron correlations and superconducting instabilities. These are approached respectively by a slave-spin theory and random phase approximation. We will discuss the possible important characters of the two materials that may hold relevance for their distinct ground states.
