Potential non-relativistic Quantum Electrodynamics and the Keldysh-Schwingerformalism is used to derive Kadanoff-Baym-like equations for two-body fieldcorrelators. These cover the out-off-equilibrium dynamics and spectrum of heavyparticle-antiparticle pairs under ultra-soft transitions inside a plasmabackground, whose temperature is much smaller compared to the typical relativepair momentum. It is shown that the dynamical equation for the pair phase-spacedistribution function, containing recombination and dissociation via theelectric dipole interactions, is consistent with the previous open quantumsystem treatment of bound states in the Coulomb limit of the two-body spectralfunction.
