Title: Polarization operator of a photon in a magnetic field

Abstract

The polarization operator of a photon in a static uniform magnetic field has been studied at photon energies both above and below the threshold of electron–positron pair production by a photon. In the first order of the fine-structure constant α, expressions for the refractive index of a photon with a certain polarization in both low and high fields as compared to the critical field H{sub 0} = 4.41 × 10{sup 13} G have been obtained. Both the purely quantum range of photon energies, where the particles of a pair are produced at the lowest Landau levels, and the region of applicability of the semiclassical approximation in the case of the population of high energy levels have been considered. A general spectral integral formula has been obtained with divergent threshold terms separated in an explicit form.

  • The authors calculated the one-loop contribution of W-bosons to the photon propagator in a constant homogeneous magnetic field. They obtain the probability for the creation of a pair of W-bosons by a polarized photon and the radiative shift of the photon mass in the external field above.
  • The absence of divergences and singularities in effectively two-dimensional field theory induced by a superstrong magnetic field is demonstrated for the example where loop diagrams involving two vector and two pseudovector vertices are calculated. The form of effective low-energy Lagrangians for ({gamma}{nu}{nu}) and (a{nu}{nu}) interactions in a superstrong magnetic field is presented. The role of photon and axion decays to neutrinos in the early universe is discussed.
  • The real photon decay, ..gamma.. ..-->.. ..nu mu..-bar, is calculated in strong magnetic fields (H approx. 10/sup 13/ G) using a version of Schwinger's mass operator technique, which makes use of the explicit form of the electron Green's function. The reaction is kinematically allowed by an index of refraction less than one. This latter condition may arise either from quantum electrodynamics (high frequencies) or from the effects of a material medium or plasma (low frequencies). The calculation is based on point-charged and neutral-current interactions for the leptons, which should agree with an SU/sub 2/ x U/sub 1/ gauge-theory calculation asmore » long as ..omega../m/sub W/ and eH/m/sub W/ /sup 2/ are both small compared to unity (where ..omega.. is the photon frequency and m/sub W/ is the mass of the W boson). Numerical results for the absorption coefficient and energy loss rate are given, since the mechanism may be important in the astrophysics of neutron stars. (AIP)« less
  • The polarization operator in (2+1)-dimensional quantum electrodynamics in an external magnetic field is calculated in the one-loop approximation. Its expansion in eigenvectors is obtained and the analytical properties of the eigenvalues are studied. In particular it turns out that, in contrast to QED{sub 3+1}, the polarization operator has simple poles at the electron-positron pair-production threshold.
