cQED detection of anisotropic pairing in a mesoscopic superconductor-ferromagnet bilayer: part I

Mesoscopic and low-dimensional materials represent one of the frontiers in the study of unconventional superconductivity. Owing to their small size, these materials are challenging to probe using conventional measurement techniques and require new experimental probes to successfully characterize them. In this talk, we introduce one such probe which enables us to measure the superfluid density of micron-size superconductors using microwave techniques drawn from circuit quantum electrodynamics (cQED). We apply this technique to a well-studied system, the superconductor-ferromagnet bilayer, where we find evidence for anisotropic induced superconductivity.
