Atomic parity violation in highly charged Ca and Pb ions
A. V. Viatkina, Ch. G. Mertens, B. Ohayon +2
We calculate parity-violation-induced E1 amplitudes for the and transitions in H- and Li-like ions of Ca, Ca, and $^{2…
High-Resolution Spectroscopy of Yb Ions
J. Jiang, A. V. Viatkina, Saaswath JK +7
Compared to other stable isotopes of , has a richer hyperfine structure, which leads to more favorable clock transitions, spectroscopic techniques for…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Calculation of isotope shifts and King plot nonlinearities in Ca
Anna V. Viatkina, Vladimir A. Yerokhin, Andrey Surzhykov
Many-body perturbation theory is implemented in order to calculate the isotope shifts of , , , , and energy levels of Ca, for even…
Parity-violation studies with partially stripped ions
Jan Richter, Anna V. Maiorova, Anna V. Viatkina +2
We present a theoretical study of photoexcitation of highly charged ions from their ground states, a process which can be realized at the Gamma Factory at CERN. Special attention i…
Nuclear polarization effects in atoms and ions
V. V. Flambaum, I. B. Samsonov, H. B. Tran Tan +1
In heavy atoms and ions, nuclear structure effects are significantly enhanced due to the overlap of the electron wave functions with the nucleus. This overlap rapidly increases wit…
Development of a recoil ion source providing slow Th ions including Th in a broad charge state distribution
Raphael Haas, Tom Kieck, Dmitry Budker +7
Ions of the isomer Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They…
Dependence of atomic parity-violation effects on neutron skins and new physics
A. V. Viatkina, D. Antypas, M. G. Kozlov +2
We estimate the relative contribution of nuclear structure and new physics couplings to the parity non-conserving spin-independent effects in atomic systems, for both single isotop…
Prediction of quantum many-body chaos in protactinium atom
A. V. Viatkina, M. G. Kozlov, V. V. Flambaum
Energy level spectrum of protactinium atom (Pa, Z=91) is simulated with a CI calculation. Levels belonging to the separate manifolds of a given total angular momentum and parity $J…
Sensitivity of Tunneling-Rotational Transitions in Ethylene Glycol to Variation of Electron-to-Proton Mass Ratio
A. V. Viatkina, M. G. Kozlov
Ethylene glycol in its ground conformation has tunneling transition with the frequency about 7 GHz. This leads to a rather complicated tunneling-rotational spectrum. Because tunnel…
