New Princeton study takes superconductivity to the edge

Catherine Zandonella, Office of the Dean for Research

The existence of superconducting currents, or supercurrents, along the exterior of a superconductor, has been surprisingly hard to find. Now, researchers at Princeton have discovered these edge supercurrents in a material that is both a superconductor and a topological semi-metal. This evidence for topological superconductivity could help provide the foundation for applications in quantum computing and other future technologies.
