Donuts, Donut Holes and Topological Superconductors
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. It features music by Dave Depper, Frequency Decree, Chad Crouch and Scott Holmes.

We all know that diamonds can hold great sentimental (and monetary) value. As luck may have it, diamonds—particularly defective ones, with little errors in their crystal structure—also hold great scientific value.
Gravity is a fixture of our everyday lives, particularly apparent when we drop a piece of toast on the kitchen floor or trip over an unseen step. Not surprisingly, physicists have studied gravity heavily over the centuries.
There’s a big unsolved mystery in physics: The cosmic balance sheet for matter in our universe just doesn’t add up. Galaxies all over space move as though they are much heavier than they appear.
