The Schwinger pair production rate in confining theories via holography
نویسندگان
چکیده
We study the Schwinger pair production in confining theories. The production rate in an external electric field E is numerically evaluated by using the holographic description. There exist two kinds of critical values of the electric field: (i) E = Ec , above which there is no potential barrier and particles are freely generated, and (ii) E = Es , below which the confining string tension dominates the electric field and the pair production does not occur. We argue the universal exponents associated with the critical behaviors.

Schwinger pair production in AdS 2
We analyze the pair production of charged particles in two-dimensional Antide Sitter space (AdS2) with a constant, uniform electric field. We compute the production rate both at a semi-classical level, viewing Schwinger pair production as a tunneling event, and at the full quantum level, by extracting the imaginary part of the one-loop amplitude. In contrast to the usual Schwinger pair producti...
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 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 کاملSchwinger Pair Production via Instantons in a Strong Electric Field
In the space-dependent gauge, each mode of the Klein-Gordon equation in a strong electric field takes the form of a time-independent Schrödinger equation with a potential barrier. We propose that the singleand multi-instantons of quantum tunneling may be related with the singleand multi-pair production of bosons and the relative probability for the no-pair production is determined by the total ...
متن کاملThermal Schwinger pair production at arbitrary coupling
We calculate the rate of thermal Schwinger pair production at arbitrary coupling in weak external fields. Our calculations are valid independently of many properties of the charged particles produced, in particular their spin and whether they are electric or magnetic. Using the worldline formalism, we calculate the logarithm of the rate to leading order in the weak external field and to all ord...
