“…Also shown are ratios ζ − /ζ + expected from different NL sources. The current data does not support the majority of NL being due to new physics or quadratic field shift, however the possibility of nuclear deformation as the main cause of NL, as discussed in [26], is still open. We discuss this further in the Supplementary Material.…”

“…[21]. We have shown that, unlike in [21], the majority of this NL cannot be explained by new physics or quadratic field shift, however it may still be accounted for by nuclear deformation [26]. Employing the GK analysis to remove the leading SM source of NL reduces the signal for NP to ∼ 2σ.…”

“…With these two experiments demonstrating comparable sensitivity to new physics (NP), it is intriguing that no King-plot NL was found in the Ca + work, but NL at the 3σ level was observed in Yb + . This discrepancy hints at nuclear effects as the source of the NL in Yb + , with the quadratic field shift suggested as a possible cause in [21] and the influence of nuclear deformation on the field shift proposed in [26].…”

We report measurements of isotope shifts for the five spinless Yb isotopes on the 6s 2 1 S0 → 5d6s 1 D2 transition using Doppler-free two-photon spectroscopy. We combine these data with existing measurements on two transitions in Yb + [Phys. Rev. Lett. 125, 123002 (2020)], where deviation from King-plot linearity showed hints of a new bosonic force carrier at the 3σ level. The combined data strongly reduces the significance of the new-physics signal. We show that the observed nonlinearity in the joint Yb/Yb + King-plot analysis can be accounted for by the deformation of the Yb nuclei.

We present a method that the atomic transition frequency measurement relies on the accurate wavemeter, optical frequency comb and stable Fabry–Pérot cavity to precisely determination of stable even isotope shift on single Yb+ ion (A=168,170,172,174,176). The 6s 2S1/2 ↔ 6p 2P1/2 and 5d 2D3/2 ↔ 6s 3[3/2]1/2 resonance dipole transition frequencies are preliminarily measured by using a wavemeter which is calibrated by the 729 nm clock laser of 40Ca+. Meanwhile, those frequencies are double checked by using optical frequency comb for correction of deviation. Ultimately, by changing frequency locking points at an ultralow expansion (ULE) cavity more slightly and monitoring the corresponding atomic fluorescence changing with 17%, we finally improved the resonant frequency uncertainty to ±6 MHz, which is one order of improvement in precision than previously published measurements on the same transitions. A King-plot analysis with sensitivity to coupling between electrons and neutrons is carried out to determine the field and mass-shift constants. Our measurement combined with existing or future isotope shift measurements can be used to determine basic properties of atomic nuclei, and to test for new forces beyond the Standard Model (SM).
