Additions and corrections

We, the named authors, hereby wholly retract this Physical Chemistry Chemical Physics correction. The original correction itself contained more information than is needed to correct the parent paper, but was still incomplete in the sense of full quantum electrodynamics.

A revised correction is provided here:

Perspectives of relativistic quantum chemistry: the negative energy cat smiles

To reveal the contribution of negative energy states to correlation, a complete derivation of the first and second order (nonradiative) QED energies for instantaneously interacting electrons is presented based on the simple rules for algebraically evaluating the Feynman diagrams. The previous equations that hold only for the special case of two electrons are hence corrected. For further details please see the following link:
