Extraordinary electromagnetic waves in a warm dense magnetoplasma

摘要

The linear dispersion relation for elliptically polarized electromagnetic waves in a dense fermionic quantum magnetoplasma is derived, taking into account the quantum forces associated with the quantum Bohm potential and the magnetization energy of the electrons due to the 1/2-electron spin effect. It is found that the quantum forces modify the wave dispersion at scales that depend upon lambda(q) = h/2m V-F and lambda B = root h/2mw(c), where h is the Planck constant divided by 2 pi, m is the electron mass, V-F is the Fermi electron thermal speed, and w(c) is the electron gyrofrequency.
