A Short Note On The Electron-Positron Pair Creation

Classical-quantum correspondence in electron-positron pair creation

We examine the creation of electron-positron pairs in a very strong force field. Using numerical solutions to quantum field theory we calculate the spatial and momentum probability distributions for the created particles. A comparison with classical mechanical phase space calculations suggests that despite the fully relativistic and quantum mechanical nature of the matter creation process, most...

Optimizing electron-positron pair production on kilojoule-class high-intensity lasers for the purpose of pair-plasma creation.

Expressions for the yield of electron-positron pairs, their energy spectra, and production rates have been obtained in the interaction of multi-kJ pulses of high-intensity laser light interacting with solid targets. The Bethe-Heitler conversion of hard x-ray bremsstrahlung [D. A. Gryaznykh, Y. Z. Kandiev, and V. A. Lykov, JETP Lett. 67, 257 (1998); K. Nakashima and H. Takabe, Phys. Plasmas 9, 1...

The Mechanics of Electron-Positron Pair Creation in the 3-Spaces Model

This paper lays out the mechanics of creation in the 3-spaces model of an electron-positron pair as a photon of energy 1.022 MeV or more is destabilized when grazing a heavy particle such as an atom's nucleus, thus converting a massless photon into two massive .511 MeV/c particles charged in opposition. An alternate process was also experimentally discovered in 1997, that involves converging tw...

Static Electron-Positron Pair Creation in Strong Fields for a Nonlinear Dirac model

We consider the Hartree-Fock approximation of Quantum Electrodynamics, with the exchange term neglected. We prove that the probability of static electron-positron pair creation for the Dirac vacuum polarized by an external field of strength Z behaves as 1 − exp(−κZ2/3) for Z large enough. Our method involves two steps. First we estimate the vacuum expectation of general quasi-free states in ter...
