Electromagnetic vortex beam dynamics in degenerate electron-positron astrophysical plasmas (2111.00589v1)
Published 31 Oct 2021 in physics.plasm-ph, astro-ph.HE, and physics.space-ph
Abstract: For degenerate astrophysical electron-positron plasmas we have considered dynamics of electromagnetic beams carrying angular momentum. It is found for arbitrary level of degeneracy such a beam having the power exceeding a certain critical value breaks up into many filaments, eventually leading to the formation of stable spatial solitons keeping zero field in the center of the structure.
