Using state-of-the-art magnetic imaging, a Cornell-led collaboration has for the first time characterized a key property of the superconducting state of a class of atomically thin materials that are too difficult to measure due to their minuscule size.

The group's paper, "Superfluid Response of an Atomically Thin Gate-Tuned van der Waals Superconductor," published April 12 in Nature Communications. The lead author is doctoral student Alexander Jarjour.
