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…
Phase-dependent Andreev molecules and superconducting gap closing in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +8
The Josephson junction (JJ) is an essential element of superconducting (SC) devices for both fundamental and applied physics. The short-range coherent coupling of two adjacent JJs…
Insulating Phase in Two-dimensional Josephson-Junction Arrays Investigated by Nonlinear Transport
Hiroki Ikegami, Yasunobu Nakamura
We present experimental investigations of transport properties in the insulating phase of two-dimensional Josephson-junction arrays (JJAs) by systematically changing the ratio of J…
Monte Carlo study of cuprate superconductors in a four-band - model: Role of orbital degrees of freedom
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
Understanding the complex phase diagram of cuprate superconductors is a long-standing challenging problem. Recent studies have shown that orbital degrees of freedom, both Cu …
Unified description of cuprate superconductors using four-band - model
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
In the 35 years since the discovery of cuprate superconductors, we have not yet reached a unified understanding of their properties, including their material dependence of the supe…
Effect of on-site Coulomb repulsion on ferromagnetic fluctuations in heavily over-doped cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Seiji Yunoki +1
We theoretically study ferromagnetic (FM) fluctuations that are experimentally observed in the heavily overdoped region of cuprate superconductors. To explore the origin of FM fluc…
