In our previous work [20],[21] we introduced a correction to the mean eld approximation of interacting Bosons. This
correction describes the evolution of pairs of particles that leave
the condensat...

In systems with a spontaneously broken continuous symmetry, the perturbative loop expansion
is plagued with infrared divergences due to the coupling between transverse and longitudinal fluctuations.A...
