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…
Enhanced tunable cavity development for axion dark matter searches using a piezoelectric motor in combination with gears
A. K. Yi, T. Seong, S. Lee +5
Most search experiments sensitive to quantum chromodynamics (QCD) axion dark matter benefit from microwave cavities, as electromagnetic resonators, that enhance the detectable axio…
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…
Extensive search for axion dark matter over 1\,GHz with CAPP's Main Axion eXperiment
Saebyeok Ahn, JinMyeong Kim, Boris I. Ivanov +33
We report an extensive high-sensitivity search for axion dark matter above 1\,GHz at the Center for Axion and Precision Physics Research (CAPP). The cavity resonant search, exploit…
Nontrivial Aharonov-Bohm effect and alternating dispersion of magnons in cone-state ferromagnetic rings
Vera Uzunova, Lukas Körber, Agapi Kavvadia +4
Soft magnetic dots in the form of thin rings have unique topological properties. They can be in a vortex state with no vortex core. Here, we study the magnon modes of such systems…
