More than 25 years since the discovery of superconductivity in strontium ruthanate (SRO), understanding the properties of this material remains as challenging as ever. Researchers now demonstrated that a SRO sample can allow the two energetically degenerate condensates of Cooper-pairs with opposite momentum to segregate in domains, with a domain wall in between where chirality changes. To use the analogy to Moses parting the sea, here the Red Sea would spontaneously part into 'magenta' and 'yellow' seas on either side.
