Even odder after twenty-three years: the superconducting order parameter puzzle of Sr2RuO4

Abstract In this short review, we aim to provide a topical update on the status of efforts to understand the superconductivity of Sr2RuO4. We concentrate on efforts to identify a superconducting order parameter symmetry that is compatible with all the major pieces of experimental knowledge of the ma...
