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…
Development of axion haloscopes for high-mass search at CAPP
SungWoo Youn, Junu Jeong, Yannis K. Semertzidis
The axion offers a well-motivated solution to two fundamental questions in modern physics: the strong CP problem and the dark matter mystery. Cavity haloscopes, exploiting resonant…
Speeding axion haloscope experiments using heterodyne-variance-based detection with a power-meter
Zhanibek Omarov, Junu Jeong, Yannis K. Semertzidis
We describe a new axion search method based on measuring the variance in the interference of the axion signal using injected photons with a power detector. The need for a linear am…
Exploiting higher-order resonant modes for axion haloscopes
Jinsu Kim, SungWoo Youn, Junu Jeong +3
The haloscope is one of the most sensitive approaches to the QCD axion physics within the region where the axion is considered to be a dark matter candidate. Current experimental s…
Comment on "Tunable Supermode Dielectric Resonators for Axion Dark-Matter Haloscopes"
Jinsu Kim, SungWoo Youn, Junu Jeong +1
We comment on a recently published paper, Phys. Rev. Applied 9, 014028 (2018), which presents frequency-tuning mechanisms for dielectric resonators and demonstrates their potential…
Magnetoresistance in copper at high frequency and high magnetic fields
Saebyeok Ahn, Sung Woo Youn, Jonghee Yoo +8
In halo dark matter axion search experiments, cylindrical microwave cavities are typically employed to detect signals from the axion-photon conversion. To enhance the conversion po…
