Photon Splitting in Strongly Magnetized Plasma
نویسنده
چکیده
The process of photon splitting, becomes allowed in the presence of strong magnetic field. We calculate the influence of magnetized plasma on the photon splitting absorption coefficient. We calculate the refraction coefficients and polarization vectors with the inclusion of the vacuum terms at an arbitrary value of the magnetic field, and then find photon splitting matrix element taking into account the terms that vanish in vacuum, but may be nonzero in the presence of plasma. We find the photon splitting rate in plasma with the density typical for a neutron star star atmosphere and identify a region of the parameter space where the plasma effects are important.

A new nonlinear electromagnetic mode in a magnetized plasma is predicted. Its existence depends on the interaction of an intense circularly polarized electromagnetic wave with a plasma, where quantum electrodynamical photon–photon scattering is taken into account. This scattering gives rise to a new coupling between the matter and the radiation. Specifically, we consider an electron– positron p...
متن کاملResonant Conversion of Photon Modes Due to Vacuum Polarization in a Magnetized Plasma: Implications for X-ray Emission from Magnetars
It is known that vacuum polarization can modify the photon propagation modes in the atmospheric plasma of a strongly magnetized neutron star. A resonance occurs when the effect of vacuum polarization on the photon modes balances that of the plasma. We show that a photon (with energy E >∼ a few keV) propagating outward in the atmosphere can convert from one polarization mode into another as it t...
متن کامل00 2 Comment on “ The Effect of Vacuum Polarization . . . in Strongly Magnetized Plasmas ” by Ozel ( astro - ph / 0203449 )
We have recently shown that in a highly magnetized neutron star atmospheric plasma, vacuum polarization can induce resonant conversion of photon polarization modes via a mechanism analogous to MSW neutrino oscillation. In a recent paper Ozel has dismissed this mode conversion effect as " mistakes ". Here we explain why our arguments/calculations of this effect are correct.
متن کاملRadiative neutrino transition ν → νγ in strongly magnetized plasma
The influence of strongly magnetized electron-positron plasma on the ra-diative neutrino transition ν → νγ is investigated. The probability and mean losses of the neutrino energy and momentum are calculated taking account of the photon dispersion and large radiative corrections near the resonance. It is shown that the combined effect of plasma and strong magnetic field decreases the probability...
متن کاملThe Effect of Vacuum Polarization and Proton Cyclotron Resonances on Photon Propagation in Strongly Magnetized Plasmas
We consider the effects of vacuum polarization and proton cyclotron resonances on the propagation of radiation through a strongly magnetized plasma. We analyze the conditions under which the photons evolve adiabatically through the resonant density and find that the adibaticity condition is satisfied for most photon energies of interest, allowing for a normal-mode treatment of the photon propag...
