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…
Multi-tesla operation of high-temperature superconducting cavities for accelerated axion dark matter searches
Danho Ahn, Jinsu Kim, Seongtae Park +10
Axion haloscopes use radio-frequency cavities immersed in a magnetic field to search for dark-matter axions, which could resolve two central puzzles in fundamental physics: the str…
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…
Probing the axion-electron coupling at cavity experiments
Deog Ki Hong, Sang Hui Im, Jinsu Kim +2
Axion dark matter induces electromagnetic radiation in conductors through nearly perpetual oscillations of electrons, driven by axion-electron interactions through the so-called ch…
Axion Dark Matter Search with Near-KSVZ Sensitivity Using the TM Mode
Sungjae Bae, Junu Jeong, Younggeun Kim +9
Dark matter remains one of the most profound mysteries in modern physics, with axions, a hypothetical particle proposed to resolve the strong CP problem, standing as a compelling c…
