Superconducting gap symmetry from Bogoliubov quasiparticle interference analysis on {Sr}${}_2${RuO}${}_4$

Shinibali Bhattacharyya, Andreas Kreisel, X. Kong +4

The nature of the superconducting order parameter in {Sr}${}_2${RuO}${}_4$ has generated intense interest in recent years. Since the superconducting gap is very small, high resolution…
