Noise limits for dc SQUID readout of high-<i>Q</i> resonators below 300 MHz Open
We present the limits on noise for the readout of cryogenic high-Q resonators using dc Superconducting Quantum Interference Devices (SQUIDs) below 300 MHz. This analysis uses realized first-stage SQUIDs (previously published), whose perfor…

Measurements of DC SQUID Damping Effects on Superconducting Resonant Circuits Open
Here, we present experimental measurements of SQUID-induced damping effects on strongly coupled, lumped-element resonators in the 500kHz–1 MHz frequency range. While dc SQUIDs are commonly used for sensitive readout of electromagnetic sign…

Proposal for a definitive search for GUT-scale QCD axions Open
The QCD axion is a leading dark matter candidate that emerges as part of the solution to the strong CP problem in the Standard Model. The coupling of the axion to photons is the most common experimental probe, but much parameter space rema…
