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…
Rotational Splittings in Diatomic Molecules of Interest to Searches for New Physics
Ayaki Sunaga, Timo Fleig
Diatomic molecules with an energetically low-lying state are attractive platforms to detect new physics beyond the Standard Model, such as parity- and time-reversal violat…
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…
Theoretical determination of the ionization potentials of ScF, YF, LaF and AcF
Aleksandra A. Kyuberis, Lukas F. Pasteka, Ephraim Eliav +4
We present a comprehensive theoretical study of the ionization potentials of the MF (M = Sc, Y, La, Ac) molecules using the state-of-the-art relativistic coupled cluster approach w…
Strong parity-violation effects induced by large-amplitude motions: A quantum-dynamics study of substituted chiral methanols
Ayaki Sunaga
An enhanced mechanism is proposed for the large-amplitude-motion-induced parity-violating frequency by integrating the exact quantum dynamics method with the relativistic electroni…
Measuring the nuclear magnetic quadrupole moment of optically trapped ytterbium atoms in the metastable state
Ayaki Sunaga, Yuiki Takahashi, Amar Vutha +1
We propose a scheme to measure a nuclear magnetic quadrupole moment (MQM), a CP-violating electromagnetic moment that appears in the nuclear sector, using the long-lived me…
Accurate theoretical determination of the ionization potentials of CaF, SrF, and BaF
A. A. Kyuberis, L. F. Pasteka, E. Eliav +6
We present a comprehensive theoretical study of the ionization potentials of the MF (M= Ca, Sr, Ba) molecules using the state-of-the-art relativistic coupled cluster approach with…
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…
Spectroscopic and Electric Properties of the TaO Molecule Ion for the Search of New Physics: A Platform for Identification and State Control
Ayaki Sunaga, Timo Fleig
The TaO cation is an attractive molecular species to search for parity- and time-reversal-violating interactions, in particular of hadronic origin. For the spectroscopic detect…
