After a long break due to the covid crisis, this new version is characterized by a new author (VD) who actually already worked on this subject in his Ph.D of 2015 entitled "The photon wave function in principle and in practice". This new version contains new results concerning the role of longitudinal e-m fields in the quantum Green function; it aims at replacing the first version of 2018 (!)

We use Glauber's correlation function as well as the Green functions formalism to investigate, in the case of a dipolar atomic transition, the causal behaviour of the spontaneously emitted electromagnetic field, in the A.p coupling. This brings us to examine the role played by the longitudinal electric field, which is not described in terms of photonic (transverse) degrees of freedom.
