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…
Expanding Scanning Frequency Range of Josephson Parametric Amplifier Axion Haloscope Readout with Schottky Diode Bias Circuit
Minsu Ko, Sergey V. Uchaikin, Boris I. Ivanov +4
The axion search experiments in the microwave frequency range require high sensitive detectors with intrinsic noise close to quantum noise limit. Josephson parametric amplifiers (J…
Four-channel System for Characterization of Josephson Parametric Amplifiers
Boris I. Ivanov, Jinmyeong Kim, Çağlar Kutlu +8
The axion search experiments based on haloscopes at the Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science (IBS) in South Korea are performed…
CAPP Axion Search Experiments with Quantum Noise Limited Amplifiers
Sergey V. Uchaikin, Boris I. Ivanov, Jinmyeong Kim +8
The axion is expected to solve the strong CP problem of quantum chromodynamics and is one of the leading candidates for dark matter. CAPP in South Korea has several axion search ex…
Josephson Parametric Amplifier in Axion Experiments
Jinmyeong Kim, Boris I. Ivanov, Çağlar Kutlu +9
The axion is a hypothetical particle, a promising candidate for dark matter, and a solution to the strong CP problem. Axion haloscope search experiments deal with a signal power co…
Search for the Sagittarius Tidal Stream of Axion Dark Matter around 4.55 eV
Andrew K. Yi, Saebyeok Ahn, Çağlar Kutlu +29
We report the first search for the Sagittarius tidal stream of axion dark matter around 4.55 eV using CAPP-12TB haloscope data acquired in March of 2022. Our result excluded the…
