Minimally Destructive Fast Imaging of Single Atoms in an Optical Tweezer Array with Coherent Excitation
Rei Yokoyama, Takumi Kashimoto, Kosuke Shibata +8
Ultracold neutral atoms in an optical lattice and an optical tweezer array offer highly-controllable quantum many-body systems, utilized for various quantum science and technology…
Excluding Hypothetical Light Boson Interpretation of Yb King Plot Nonlinearity with the Isotope Shift Measurement
Taiki Ishiyama, Koki Ono, Reiji Asano +6
We present precision spectroscopy and isotope shift measurement of the clock transition in neutral ytterbium () atoms. By revealing a…
Orders-of-magnitude improvement in precision spectroscopy of an inner-shell orbital clock transition in neutral ytterbium
Taiki Ishiyama, Koki Ono, Hokuto Kawase +6
An inner-shell orbital clock transition in neutral ytterbium atoms has attracted much attention as a new optical frequency standard a…
Development of a high-power ultraviolet laser system and observation of fast coherent Rydberg excitation of ytterbium
Yuma Nakamura, Naoya Ozawa, Toshi Kusano +5
We present the development of a high-power ultraviolet laser system operating at a wavelength of 325 nm for Rydberg excitation from the state of ytterbium. Utili…
Observation of an Inner-Shell Orbital Clock Transition in Neutral Ytterbium Atoms
Taiki Ishiyama, Koki Ono, Tetsushi Takano +2
We observe a weakly allowed optical transition of atomic ytterbium from the ground state to the metastable state for all five bosonic and two fermionic iso…
Observation of non-linearity of generalized King plot in the search for new boson
Koki Ono, Yugo Saito, Taiki Ishiyama +6
We measure isotope shifts for neutral Yb isotopes on an ultranarrow optical clock transition with an accuracy of a few Hz. The part-per-billion…
