On Electron-Positron Pair Production by a Spatially Nonuniform Electric Field
A. Chervyakov, H. Kleinert
A detailed analysis of electron-positron pair creation induced by a spatially nonuniform and static electric field from vacuum is presented. A typical example is provided by the Sa…
Exact Pair Production Rate for a Smooth Potential Step
A. Chervyakov, H. Kleinert
We derive the exact rate of pair production of oppositely charged scalar particles by a smooth potential proportional to tanh kz in three dimensions. As a check we recover from thi…
Reparametrization Invariance of Path Integrals
H. Kleinert, A. Chervyakov
We demonstrate the reparametrization invariance of perturbatively defined one-dimensional functional integrals up to the three-loop level for a path integral of a quantum-mechanica…
Evidence for Negative Stiffness of QCD Strings
H. Kleinert, A. M. Chervyakov
QCD strings are color-electric flux tubes between quarks with a finite thickness and thus a finite curvature stiffness. Contrary to an earlier rigid-string by Polyakov and Kleinert…
Is it possible to assign physical meaning to field theory with higher derivatives?
A. M. Chervyakov, V. V. Nesterenko
To overcome the difficulties with the energy indefiniteness in field theories with higher derivatives, it is supposed to use the mechanical analogy, the Timoshenko theory of the tr…
