The Rydberg-Atom-Cavity Axion Search
K. Yamamoto, M. Tada, Y. Kishimoto +8
We report on the present progress in development of the dark matter axion search experiment with Rydberg-atom-cavity detectors in Kyoto, CARRACK I and CARRACK II. The axion search…
A coupled microwave-cavity system in the Rydberg-atom cavity detector for dark matter axions
M. Tada, Y. Kishimoto, M. Shibata +5
A coupled microwave-cavity system of cylindrical TM single-mode has been developed to search for dark matter axions around 10 (2.4 GHz) with the Rydberg-atom cav…
Coherent time evolution of highly excited Rydberg states in pulsed electric field: Opening a stringent way to selectively field-ionize the highly excited states
M. Tada, Y. Kishimoto, I. Ogawa +3
Coherent time evolution of highly excited Rydberg states in Rb (98 < n < 150) under pulsed electric field in high slew-rate regime was investigated with the field ionization detect…
Quantum analysis of Rydberg atom cavity detector for dark matter axion search
Akira Kitagawa, Katsuji Yamamoto, Seishi Matsuki
Quantum calculations are developed on the dynamical system consisting of the cosmic axions, photons and Rydberg atoms which are interacting in the resonant microwave cavity. The ti…
Quantum Analysis of Rydberg Atom Cavity Detector for Dark Matter Axion Search
K. Yamamoto, S. Matsuki
Quantum analysis is made on the dynamical system consisting of the cosmic axions, photons and Rydberg atoms which are interacting in the resonant cavity. The atomic motion in a con…
