Cryogenic RF characterization of the MAGO cavity for high-frequency gravitational-wave detection
Can Dokuyucu, Bianca Giaccone, Tom Krokotsch +13
Superconducting radio-frequency (SRF) cavities are promising resonant sensors for gravitational-wave detection in the kHz-MHz frequency range. We report the cryogenic RF characteri…
Improved Dark Photon Sensitivity from the Dark SRF Experiment
Saarik Kalia, Zhen Liu, Bianca Giaccone +15
We report the refined dark-photon exclusion bound from Dark SRF's pathfinder run. Our new result is driven by improved theoretical modeling of frequency instability in high-quality…
First characterisation of the MAGO cavity, a superconducting RF detector for kHz-MHz gravitational waves
Lars Fischer, Bianca Giaccone, Ivan Gonin +12
Heterodyne detection using microwave cavities is a promising method for detecting high-frequency gravitational waves or ultralight axion dark matter. In this work, we report on stu…
A Precision Gyroscope from the Helicity of Light
Michael A. Fedderke, Roni Harnik, David E. Kaplan +4
We describe a gyroscope that measures rotation based on the effects of the rotation on the polarization of light. Rotation induces a differential phase shift in the propagation of…
An Improved Bound on Nonlinear Quantum Mechanics using a Cryogenic Radio Frequency Experiment
Oleksandr Melnychuk, Bianca Giaccone, Nicholas Bornman +9
There are strong arguments that quantum mechanics may be nonlinear in its dynamics. A discovery of nonlinearity would hint at a novel understanding of the interplay between gravity…
