Coherent Detection at the Quantum Frontier: From Axion Dark Matter to Precision Spin Physics
The next generation of precision experiments in particle physics increasingly relies on coherent detection methods capable of extracting extremely weak signals buried far below conventional noise levels. In this talk, I will discuss how techniques developed in storage-ring spin physics and axion dark matter research are converging toward a broader framework of coherent RF phase-sensitive detection.
Topics will include resonant probing methods, high-(Q) RF systems, electro-optic transduction, coherent phase extraction, and quantum-limited sensing strategies. Particular emphasis will be placed on the CARAMEL concept and on possible implementations for high-frequency axion dark matter searches using high temperature superconducting (HTS) cavities, cryogenic RF systems, and optical readout architectures.
I will also discuss opportunities for developing a broader European effort combining accelerator physics, including storage-ring proton EDM studies with sensitivities approaching the Standard Model level, RF engineering, cryogenics, quantum electronics, and advanced detector technologies, with potential participation from Demokritos and collaborating institutes.
