The proton structure effects, including finite size, polarizability and self– energy is considered and their influence on energy levels of muonic hydrogen is recalculated. A new theoretical prediction for the Lamb shift is presented together with improved values of all known QED contributions.

Proton structure effects in hydrogenic bound states are analyzed using nonrelativistic QED effective field theory. Implications for the Lamb shift in muonic hydrogen are discussed. Model-dependent assumptions in previous analyses are isolated, and sensitivity to poorly constrained hadronic structure in the two-photon exchange contribution is identified.

We study the quantum dynamics of an ion confined in a radiofrequency trap interaction with either Bose or spin-polarized Fermi gas. To this end, we derive optical master equations limit weak coupling and Lamb-Dicke approximations. For bosonic bath, also include so-called "Lamb-shift" correction to due gas as well extended Fr\"ohlich within Bogolyubov approximation that have been not considered ...
