Topology—the mathematical study of shapes that describes how a donut differs from a donut hole—has turned out to be remarkably relevant to understanding our physical world. For decades, it’s captured the hearts and minds of physicists, who have spent that time uncovering just how deep the connection between topology and physics runs. Among many other things, they’ve unearthed a prediction, born of topology, for a new particle with promising applications to quantum computing.In this episode of Relatively Certain, Dina Genkina sits down with JQI Fellow Jay Sau, an associate professor of physics at UMD, and Johnpierre Paglione, a professor of physics at UMD and the director of the Quantum Materials Center. They take a trip back to the 1980s, when the story of topology in physics began, and arrive at a recent discovery by Paglione and his collaborators of a (possible) topological superconductor.This episode of Relatively Certain was produced by Dina Genkina, Chris Cesare, and Emily Edwards.
