Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
Quantum metrology of low frequency electromagnetic modes with frequency upconverters
Stephen E. Kuenstner, Elizabeth C. van Assendelft, Saptarshi Chaudhuri +11
We present the RF Quantum Upconverter (RQU) and describe its application to quantum metrology of electromagnetic modes between dc and the Very High Frequency band (VHF) (…
Dispersive readout of a high-Q encapsulated micromechanical resonator
Nicholas E. Bousse, Stephen E. Kuenstner, James M. L. Miller +4
Encapsulated bulk mode microresonators in the megahertz range are used in commercial timekeeping and sensing applications but their performance is limited by the current state of t…
Bandwidth and Aliasing in the Microwave SQUID Multiplexer
Cyndia Yu, Zeeshan Ahmed, Jake A. Connors +13
The microwave SQUID multiplexer (umux) has enabled higher bandwidth or higher channel counts across a wide range of experiments in particle physics, astronomy, and spectroscopy. Th…
Projected Sensitivity of DMRadio-m: A Search for the QCD Axion Below eV
DMRadio Collaboration, L. Brouwer, S. Chaudhuri +31
The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass (), axion dark ma…
New Horizons: Scalar and Vector Ultralight Dark Matter
D. Antypas, A. Banerjee, C. Bartram +123
The last decade has seen unprecedented effort in dark matter model building at all mass scales coupled with the design of numerous new detection strategies. Transformative advances…
Introducing DMRadio-GUT, a search for GUT-scale QCD axions
L. Brouwer, S. Chaudhuri, H. -M. Cho +29
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 mo…
An Impedance-Modulated Code-Division Microwave SQUID Multiplexer
C. Yu, A. Ames, S. Chaudhuri +5
Large arrays of cryogenic detectors, including transition-edge sensors (TESs) or magnetic micro-calorimeters (MMCs), are needed for future experiments across a wide range of applic…
Microwave multiplexing on the Keck Array
Ari Cukierman, Zeeshan Ahmed, Shawn Henderson +82
We describe an on-sky demonstration of a microwave-multiplexing readout system in one of the receivers of the Keck Array, a polarimetry experiment observing the cosmic microwave ba…
Exclusion Limits on Hidden-Photon Dark Matter near 2 neV from a Fixed-Frequency Superconducting Lumped-Element Resonator
A. Phipps, S. E. Kuenstner, S. Chaudhuri +10
We present the design and performance of a simple fixed-frequency superconducting lumped-element resonator developed for axion and hidden photon dark matter detection. A rectangula…
Highly-multiplexed microwave SQUID readout using the SLAC Microresonator Radio Frequency (SMuRF) Electronics for Future CMB and Sub-millimeter Surveys
