Schwinger mechanism revisited

Abstract: In this article, we review recent theoretical works on the Schwinger mechanism of particle production in external electrical fields. Although the non-perturbative Schwinger mechanism is at the center of this discussion, many of the approaches that we discuss can cope with general time and space dependent fields, and therefore also capture the perturbative contributions to particle production.

“…In contrast, initial inhomogeneous electric fields can be given by zero gauge field A(0) = 0, and thus they can be consistent with the free initial condition for spinors. In the τ -η coordinates, one can construct the initial condition for the spinors at τ = 0 that is consistent with the evolution of the gauge fields describing a collision of color glass condensates [30]. In this case, the existence of the initial magnetic fields does not cause the inconsistency.…”

“…Also in flat space there are closely related processes: in Schwinger pair creation particles are produced due to a background electric field [44] (for a recent review, see [45]) and in the Unruh effect because of constant acceleration [46]. A crucial conclusion from Hawking radiation is that black holes may be viewed as thermodynamic objects, which is manifested as the relation between the event horizon area and entropy of a black hole [47][48][49][50][51][52].…”

“…The results are however interesting enough to suggest that a more detailed computation of pre-equilibrium photon production rates is desirable. When gluon occupancies are large, this can be achieved by using classical-statistical simulations including dynamical quarks [48][49][50] 3 . First results for the photon production from color background fields in a fixed box geometry are now available [54].…”
