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…
Continuous coherent spin-frequency metrology in storage rings via resonant beam-driven detection
Younggeun Kim, Themis Bowcock, Dmitry Budker +24
Precision measurements in storage rings are increasingly limited by the ability to monitor collective spin dynamics coherently over long time scales. Existing polarimetry technique…
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…
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…
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…
Search for Dark Matter Axions with Tunable TM_020 mode
Sungjae Bae, Junu Jeong, Younggeun Kim +5
Axions are hypothesized particles believed to potentially resolve two major puzzles in modern physics: the strong CP problem and the nature of dark matter. Cavity-based axion halos…
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…
Experimental search for invisible dark matter axions around 22 μeV
Younggeun Kim, Junu Jeong, SungWoo Youn +9
The axion has emerged as the most attractive solution to two fundamental questions in modern physics related to the charge-parity invariance in strong interactions and the invisibl…
A machine learning algorithm for direct detection of axion-like particle domain walls
Dongok Kim, Derek F. Jackson Kimball, Hector Masia-Roig +6
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) conducts an experimental search for certain forms of dark matter based on their spatiotemporal signa…
Cosmic Axion Force
Dongok Kim, Younggeun Kim, Yannis K. Semertzidis +2
Nambu-Goldstone bosons, or axions, may be ubiquitous. Some of the axions may have small masses and thus serve as mediators of long-range forces. In this paper, we study the force m…
Sensitivity improvement in hidden photon detection using resonant cavities
Younggeun Kim, SungWoo Youn, Danho Ahn +3
Analogous to the light-shining-through-wall setup proposed for axion-like particle searches, a pair of resonant cavities have been considered to search for an extra U(1) massive ga…
Revisiting the detection rate for axion haloscopes
Dongok Kim, Junu Jeong, SungWoo Youn +2
The cavity haloscope has been employed to detect microwave photons resonantly converted from invisible cosmic axions under a strong magnetic field. In this scheme, the axion-photon…
Compact ultracold neutron source concept for low energy accelerator-driven neutron sources
Yun Chang Shin, W. Michael Snow, David V. Baxter +4
The concept of a small-scale, pulsed-proton accelerator based compact ultracold neutron (UCN) source is presented. The essential idea of the compact UCN source is to enclose a volu…
Effective Approximation of Electromagnetism for Axion Haloscope Searches
Younggeun Kim, Dongok Kim, Junu Jung +3
We applied an effective approximation into Maxwell's equations with an axion interaction for haloscope searches. A set of Maxwell's equations acquired from this approximation descr…
