Abstract
There is presently a great interest in studying QED effects in highly charged ions by means of large accelerators, and the best information is usually gained from the study of multi-electron ions. It might then be possible to detect the combined effect of QED and electron correlation, which has so far never been observed. That could be possible also from accurate laser or X-ray data. For the corresponding theoretical analysis it will then be necessary to treat the effects of QED and electron correlation simultaneously in a coherent manner. This is not possible with presently available techniques but will require the new generation of atomic calculations that is now being developed at our laboratory. The calculations have to be performed in the Coulomb gauge, and a procedure for renormalization in that gauge has very recently been tested for hydrogen-like ions. Work is now in progress to perform unified MBPT-QED calculations on multi-electron systems.
