Superconducting gap in the one-dimensional bands in 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. In our previous experiment we observe that the nesting induced fluctuations clearly persist in the superconducting state for energies significantly below 2delta, which strongly suggests that the 1d bands are not the active bands in the superconducting pairing. We want to continue with our studies in order to obtain clear information about the nature and size of the superconducting gap on the 1d bands.
