Edge states of Sr${}_2$RuO${}_4$ detected by in-plane tunneling spectroscopy

Satoshi Kashiwaya, Hiromi Kashiwaya, Hiroshi Kambara +4

We perform tunneling spectroscopy of Sr${}_2$RuO${}_4$ searching for the edge states peculiar to topological superconductivity. Conductance spectra obtained on Sr${}_2$RuO${}_4$/Au junctio…
