Light Propagation Effects In QED: Effective Action Approach
The effects of light propagation in constant magnetic and electric backgrounds are considered in the framework of the effective action approach. We use the exact analytic series representation for the one-loop effective action of QED and apply it to the birefringence effect. Analytical results for the light velocity modes are obtained for weak and strong field regime. We present asymptotic form...
متن کاملQED Effective Action Revisited
The derivation of a convergent series representation for the quantum electrodynamic effective action obtained by two of us (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 w...
متن کاملPhenomenological Analysis of Shock-Wave Propagation in Weakly Ionized Plasmas
Shock propagation into weakly ionized gases shows several features differing markedly from conventional, nonionized-gas shock structure. Phenomenological analysis of general macroscopic features of the previously observed plasma shock effects allows only two possible interpretations: existence of an energy (momentum) flux toward the wave precursor or volumetric energy release (exothermic phase ...
متن کاملEffective Action and Schwinger Pair Production in Strong QED
Some field theoretical aspects, such as the effective action and Schwinger pair production, are critically reviewed in strong QED. The difference of the boundary conditions on the solutions of the field equation is discussed to result in the effective action both in the Coulomb and time-dependent gauge. Finally, the apparent spin-statistics inversion is also discussed, where the WKB action for ...
متن کاملScalar Quartic Effective Action on AdS5
We review the recent results concerning the computation of cubic and quartic couplings of scalar fields in type IIB supergravity on AdS5 × S background that are dual to (extended) chiral primary operators in N = 4 SYM4. We discuss the vanishing of certain cubic and quartic couplings and non-renormalization property of corresponding correlators in the conformal field theory.
