Observation of the clock transition at 431 nm in Yb
Akio Kawasaki, Takumi Kobayashi, Akiko Nishiyama +2
We report on the observation of the transition at 431 nm in Yb by depleting atoms in a magneto-optical trap formed by the $6s^{2…
Search for ultralight dark matter from long-term frequency comparisons of optical and microwave atomic clocks
Takumi Kobayashi, Akifumi Takamizawa, Daisuke Akamatsu +8
We search for ultralight scalar dark matter candidates that induce oscillations of the fine structure constant, the electron and quark masses, and the quantum chromodynamics energy…
Dual-comb cavity ring-down spectroscopy
D. Lisak, D. Charczun, A. Nishiyama +10
Cavity ring-down spectroscopy is a ubiquitous optical method used to study light-matter interactions with high resolution, sensitivity and accuracy. However, it has never been perf…
Ultra-high finesse cavity-enhanced spectroscopy for accurate tests of quantum electrodynamics for molecules
M. Zaborowski, M. Słowiński, K. Stankiewicz +11
We report the most accurate measurement of the position of the weak quadrupole S(2) 2-0 line in D. The spectra were collected with a frequency-stabilized cavity ring-down spect…
