Pair creation: back-reactions and damping
Abstract
We solve the quantum Vlasov equation for fermions and bosons, incorporating spontaneous pair creation in the presence of back-reactions and collisions. Pair creation is initiated by an external impulse field and the source term is non-Markovian. A simultaneous solution of Maxwell's equation in the presence of feedback yields an internal current and electric field that exhibit plasma oscillations with a period taupl. Allowing for collisions, these oscillations are damped on a time-scale, taur, determined by the collision frequency. Plasma oscillations cannot affect the early stages of the formation of a quark-gluon plasma unless taur >> taupl and taupl approx. 1/LambdaQCD approx 1 fm/c.
