With pulses of sound through tiny speakers, Cornell physics researchers have clarified the basic nature of a new superconductor. Since it was found to be a superconductor about five years ago, uranium ditelluride has created a lot of buzz in the quantum materials community—and a lot of confusion, with more than a dozen theories about the true nature of its superconducting properties. Some suggested valuable possibilities for quantum computing. In an experiment, Brad Ramshaw, associate professor of physics in the College of Arts and Sciences (A&S) and colleagues have used ultrasound to gather direct evidence that uranium ditelluride has a single-component superconducting order parameter, ruling out a more exotic type of superconductor that would have been exciting news for quantum computing. But setting a baseline of data for the material's intrinsic superconductivity still leaves the...read more...
