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…
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…
Observation of spin-space quantum transport induced by an atomic quantum point contact
Koki Ono, Toshiya Higomoto, Yugo Saito +3
Quantum transport is ubiquitous in physics. So far, quantum transport between terminals has been extensively studied in solid state systems from the fundamental point of views such…
Observation of spin-exchange dynamics between itinerant and localized atoms
Koki Ono, Yoshiki Amano, Toshiya Higomoto +2
We report on the observation of the spin-exchange dynamics of atoms in the ground state and in the metastable state . We implem…
