“…Pair conversion by photons and pair emission by electrons propagating in the field has been studied under similar conditions [48,[57][58][59][60][61][62][63]. Even the effective neutrino-photon coupling and the axial anomaly have received attention [64][65][66][67].…”

The long-standing challenge to describing charged particle dynamics in strong classical electromagnetic fields is how to incorporate classical radiation, classical radiation reaction and quantized photon emission into a consistent unified framework. The current, semiclassical methods to describe the dynamics of quantum particles in strong classical fields also provide the theoretical framework for fundamental questions in gravity and hadron-hadron collisions, including Hawking radiation, cosmological particle production and thermalization of particles created in heavy-ion collisions. However, as we show, these methods break down for highly relativistic particles propagating in strong fields. They must therefore be improved and adapted for the description of laser-plasma experiments that typically involve the acceleration of electrons. Theory developed from quantum electrodynamics, together with dedicated experimental efforts, offer the best controllable context to establish a robust, experimentally validated foundation for the fundamental theory of quantum effects in strong classical potentials.

“…Unfortunately, such a simple formula for the axialvector current j µ 5 does not exist, so it must be calculated from first principles. This has been achieved recently in [20] for arbitrarily strong electromagnetic background fields in a first-order gradient expansion. The necessary basic equation is the relation between the axialvector current and the axialvector-vector amplitude, i.e., the axial analogue of the polarization tensor,…”

The construction of low-energy effective actions in QED for several types of external conditions is reviewed. Emphasis is put on the application of these effective actions to a variety of physical effects which represent a manifestation of vacuum polarization. Soft-photon interactions with external electromagnetic fields and/or a heat bath are described, pair production at finite temperature is discussed, and finally a glance at photon-neutrino interactions is provided.

“…Moreover, standard-model calculations in constant electromagnetic fields can always be checked by testing their dual invariance; e.g. in [57,58], this dual invariance is visible in neutrino amplitudes in electromagnetic fields. Of course, to be on the safe side, the duality of Type II suffices for such a check in order to avoid problems of the kind mentioned before.…”

The derivation of a convergent series representation for the quantum electrodynamic effective action obtained by two of us (S.R.V. and D.R.L.) in [Can. J. Phys. 71, 389 (1993)] is reexamined. We present more details of our original derivation. Moreover, we discuss the relation of the electric-magnetic duality to the integral representation for the effective action, and we consider the application of nonlinear convergence acceleration techniques which permit the efficient and reliable numerical evaluation of the quantum correction to the Maxwell Lagrangian.

Axial vector current in an electromagnetic field and low-energy neutrino-photon interactions

Abstract: An expression for the axial vector current in a strong, slowly varying electromagnetic field is obtained. We apply this expression to the construction of the effective action for low-energy neutrino-photon interactions.
