    emphasized textIn this contribution, we discuss the theory of the bound-electron g factor. This quantity can be measured nowadays to high precision in Penning-trap setups. The collaboration of theory and experiment enables impactful and detailed tests of quantum electrodynamics in a strong background electric field, and a competitive determination of fundamental constants [1] and nuclear...

    quantum electrodynamics of bound systems
    Oral presentation

    Hard spin-independent three-loop radiative corrections to energy levels in muonium and positronium are calculated.
    These corrections could be relevant for the new generation of precise 1S-2S and 2S-2P measurements in muonium and
    positronium.
