“Studying the electrical response of a superconductor as one drives a large current through it is essential for characterizing superconducting circuits, but there is a lot of microscopic information of what’s happening inside the material that’s left to reveal,” he says. “The nanoscale physics of superconductors under operational conditions, namely when large currents are passed through them, is exactly what we’re interested in elucidating.”

“This is in a way a new direction where we’re not just studying the material in its undisturbed state, let’s say, just as a function of temperature, but without applying any sort of perturbation like a current or a field. Now we’re moving into a direction where we’re studying what happens in materials as they are driven at conditions of large currents, which are very close to those one would find inside a device or machine based on these superconducting circuits,” Comin explains.

Unlike niobium-tin alloys that require liquid helium cooling (about 4 kelvins) in MRI machines, YBCO superconducts at the somewhat higher temperature of liquid nitrogen. This is significant because liquid nitrogen (about 77 kelvins, or -320.4 degrees Fahrenheit) is both more abundant and considerably cheaper to use than helium, Comin says.
