Mass defect of electronic transitions in atoms and ions — Simon Eilers, •Víctor J. Martínez-Lahuerta, Marius Schulte, and Klemens Hammerer — Institute for Theoretical Physics and Institute for Gravitational Physics (Albert-Einstein-Institute), Leibniz University Hannover, Appelstrasse 2, 30167 Hannover, Germany

In this work we will present a low-order relativistic correction to the multipolar atom-light Hamiltonian for two bound particles corresponding to a simple model for Hydrogen-like atoms and ions. From this result we can systematically predict frequency shifts in atomic clocks based on trapped ions due to the mass defect and the quadrupole effect caused by external fields, as recently discussed by V. Yudin and A. V. Taichenachev (Laser Phys. Lett. 15, 035703, 2018).
