Standing electromagnetic solitons in degenerate relativistic plasmas

• We study the standing electromagnetic (EM) solitons in the fully degenerate electron plasma.
• The theory is based on the manifestly covariant Maxwell–Fluid model equations.
• We show that the stable standing solitons exist for arbitrary level of plasma degeneracy.

The existence of standing high frequency electromagnetic (EM) solitons in a fully degenerate overdense electron plasma is studied applying relativistic hydrodynamics and Maxwell equations. The stable soliton solutions are found in both relativistic and nonrelativistic degenerate plasmas.
