Photon Orbital Angular Momentum and Proca effects in rotating and charged spacetimes | F. Tamburini

1 Sep 2011 | Abstract: | We analyze the effect of Proca mass and orbital angular momentum of photons
imposed by a structured plasma in Kerr-Newman and Reissner-Nordstrom-de Sitter
spacetimes. The presence of characteristic lengths in a turbulent plasma
converts the virtual Proca photon mass on orbital angular momentum, with the
result of decreasing the virtual photon mass. The combination of this plasma
effect and that of the gravitational field leads to a new astrophysical
phenomenon that imprints a specific distribution of orbital angular momentum
into different frequencies of the light emitted from the neighborhood of such a
black hole. The determination of the orbital angular momentum spectrum of the
radiation in different frequency bands leads to a complete characterization of
the electrostatic and gravitational field of the black hole and of the plasma
turbulence, with fundamental astrophysical and cosmological implications. | Source: | arXiv, 1109.0140 | Services: | Forum | Review | PDF | Favorites |
