Abstract

<p>Recent development in the atomic physics enabled us to perform extremely high precision spectroscopy, as high as 10-18 relative precision, and with this high precision, eV-scale phenomena have an access to high energy physics. Among atoms that are commonly used for these high precision spectroscopies, ytterbium has various features that are suitable for applications for the fundamental physics: several narrowlinewidth transitions for both neutral atoms and ions, seven stable isotopes, and transitions involving f orbitals. Specifically, ytterbium has so far been used for ultralight dark matter searches by atomic clock comparisons, new boson searches through precision isotope shift measurements, and searches for time variations of fundamental constants. Further improvements in the precision of the spectroscopies are expected to enhance the regions of these searches, and features for ytterbium atoms can be utilized for investigating other new physics.</p>
