Extended quasiparticle approximation for relativistic electrons in plasmas
Starting with Dyson equations for the path-ordered Green’s function, it is shown that the correlation functions for relativistic electrons (positrons) in a weakly coupled non-equilibrium plasmas can be decomposed into sharply peaked quasiparticle parts and off-shell parts in a rather general form....

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Starting with Dyson equations for the path-ordered Green’s function, it is shown that the correlation functions
for relativistic electrons (positrons) in a weakly coupled non-equilibrium plasmas can be decomposed
into sharply peaked quasiparticle parts and off-shell parts in a rather general form. To leading order in the
electromagnetic coupling constant, this decomposition yields the extended quasiparticle approximation for the
correlation functions, which can be used for the first principle calculation of the radiation scattering rates in
QED plasmas. |
