Abstract

<abstract> <title>Abstract</title> <p>The combined effect of special relativity and electron degeneracy on Langmuir waves is analyzed by utilizing a rigorous fully relativistic hydrodynamic model. Assuming a traveling wave solution form, a set of conservation laws is identified, together with a pseudo-potential function depending on the relativistic parameter <italic>p</italic>_F/(<italic>m</italic><italic>c</italic>) (where <italic>p</italic>_F is the Fermi momentum, <italic>m</italic> is the mass of the charge carriers and <italic>c</italic> the speed of light), as well as on the amplitude of the electrostatic energy perturbation.</p> </abstract>
