Radiation signal accompanying the Schwinger effect

چکیده
The properties of the forced oscillations electron-positron plasma (EPP) generated from vacuum under action a short laser pulse are considered. Calculating density conduction and polarization currents within quantum kinetic approach, we demonstrate presence at frequency external field its odd harmonics. It is expected that radiation by these can be observed outside interaction region, for example, focal spot two counterpropagating beams, serve as an indicator Schwinger mechanism EPP creation vacuum.

Schwinger Effect in String Theory
I discuss the quantum instability of an electric field in a theory of open strings. One of the few available hints on the interplay between quantum theory and gravity is the Hawking emission of a black hole 1. This can be described as pair creation in the background gravitational field. Of the two produced particles one stays trapped inside the horizon, while the other escapes to infinity where...
متن کاملInflationary Perturbations: the Cosmological Schwinger Effect
This pedagogical review aims at presenting the fundamental aspects of the theory of inflationary cosmological perturbations of quantum-mechanical origin. The analogy with the well-known Schwinger effect is discussed in detail and a systematic comparison of the two physical phenomena is carried out. In particular, it is demonstrated that the two underlying formalisms differ only up to an irrelev...
متن کاملNotes on holographic Schwinger effect
We use the method of evaluating the decay rate in terms of the imaginary part of a probe brane action to study the holographic Schwinger effect. In the confining D3-branes case, we find that the Schwinger effect occurs at energy scales higher than the Kaluza-Klein mass, indicating the absence of such effect when the dual gauge field theory can be regarded as an 2+1 dimensional theory. This prop...
متن کاملHolographic Schwinger effect and the geometry of entanglement.
We show that the recently proposed bulk dual of an entangled pair of a quark and an antiquark corresponds to the Lorentzian continuation of the tunneling instanton describing Schwinger pair creation in the dual field theory. This observation supports and further explains the claim by Jensen and Karch that the bulk dual of an Einstein-Podolsky-Rosen pair is a string with a wormhole on its world ...
متن کاملThe Schwinger mass in the massive Schwinger model
We derive a systematic procedure to compute Green functions for the massive Schwinger model via a perturbation expansion in the fermion mass. The known exact solution of the massless Schwinger model is used as a starting point. We compute the corrections to the Schwinger mass up to second order. ∗)permanent address: Institut für theoretische Physik, Universität Wien Boltzmanngasse 5, 1090 Wien,...
