Existence of a resonance mode in superconducting Sr2RuO4
There is ongoing debate about the symmetry of the superconducting order parameter in Sr2RuO4 which is one of the most promising materials for topological superconductivity. Also the question which electronic bands drive and which follow superconductivity remains subjects of controversy. We propose to search for a resonance mode or for a shift of spectral weight in the superconducting state in Sr2RuO4 in order to verify or falsify clear predictions made by theory.
