Extended High-Mass Axion Search with an Auxetically Tuned Higher-Order-Mode Cavity
Jinsu Kim, Sungjae Bae, Junu Jeong +9
Conventional high-mass axion haloscopes based on the TM mode lose detection volume as the resonant frequency increases. We report an extended axion search using a dielectri…
Search for Axion Dark Matter around \texorpdfstring{}{15.6 microeV} with a Broadly Tunable High-Temperature Superconducting Cavity
Jiwon Lee, Jinsu Kim, Ohjoon Kwon +9
We report an axion dark matter search in the mass range of using a broadly tunable high-temperature superconducting (HTS) haloscope. By soldering…
Extended Haloscope Search and Exclusion of a Candidate Signal near 1.036 GHz
Saebyeok Ahn, Boris I. Ivanov, Ohjoon Kwon +33
We report a follow-up axion haloscope search near 1.036 GHz that completes and extends our previous work [Phys. Rev. X 14, 031023 (2024)], in which a portion of the HEMT-based data…
Josephson Parametric Amplifier based Quantum Noise Limited Amplifier Development for Axion Search Experiments in CAPP
Sergey V. Uchaikin, Jinmyeong Kim, Caglar Kutlu +8
This paper provides a comprehensive overview of the development of flux-driven Josephson Parametric Amplifiers (JPAs) as Quantum Noise Limited Amplifier for axion search experiment…
Parameter optimization of Josephson parametric amplifiers using a heuristic search algorithm for axion haloscope search
Younggeun Kim, Junu Jeong, SungWoo Youn +5
The cavity haloscope is among the most widely adopted experimental platforms designed to detect dark matter axions with its principle relying on the conversion of axions into micro…
Characterization of a flux-driven Josephson parametric amplifier with near quantum-limited added noise for axion search experiments
Çağlar Kutlu, Arjan F. van Loo, Sergey V. Uchaikin +7
The axion, a hypothetical elementary pseudoscalar, is expected to solve the strong CP problem of QCD and is also a promising candidate for dark matter. The most sensitive axion sea…
