Radiation Pressure Effect on the degenerate Electron-Positron Plasma Dynamics
Irakli Ugulava, Vazha Berezhiani
We investigate the influence of radiation pressure on the collective dynamics of a degenerate electron--positron plasma interacting with an intense radiation flux. Assuming the Fer…
Vortex Solitons and Filamentation of Electromagnetic Beams in Relativistically Degenerate Plasmas
Nikolai Maltsev, Vazha I. Berezhiani
We study the propagation and stability of electromagnetic vortex beams in relativistically de generate plasmas. We show that such plasmas support localized vortex solitons carrying…
On Lorentz Variability of Magnetically Dominated Relativistic Outflows
V. I. Berezhiani, N. L. Shatashvili, A. G. Tevzadze
We show that magnetized relativistic outflows can exhibit a relativistic effect in which Lorentz transformation maps spatially extended magnetic field structure into apparent tempo…
Electromagnetic vortex beam dynamics in degenerate electron-positron astrophysical plasmas
V. I. Berezhiani, Z. N. Osmanov, S. V. Mikeladze
For degenerate astrophysical electron-positron plasmas we have considered dynamics of electromagnetic beams carrying angular momentum. It is found for arbitrary level of degeneracy…
Prospects of SETI by small size optical telescopes
Z. N. Osmanov, V. I. Berezhiani
In the present manuscript we consider the possibility of SETI by the small size (with diameters less than 1 m) optical telescopes. Calculations are performed for typical parameters…
Solitary structure formation and self-guiding of electromagnetic beam in highly degenerate electron plasma
V. I. Berezhiani, Z. N. Osmanov, S. M. Mahajan +1
In the present paper we consider the nonlinear interaction of high frequency intense electromagnetic (EM) beam with degenerate electron plasmas. In a slowly varying envelop approxi…
