The Propagation Characteristics Of Linear Waves In Intense-solid Astrophysics Plasmas

The plasmas composed of relativistic degenerate electrons and non-relativistic ions are called relativistic degenerate plasmas.The intense-solid astrophysics objets is one of relativistic degenerate plasmas,such as the interior of massive white dwarfs and the atmospheres of neutron stars.Due to the condition of number density of electrons,the study of relativistic degenerate plasmas has been limited to the above extreme astrophysical environment for a long time.It is well known that the mechanism of astrophysical phenomena and process is related to the fluctuation and instability in plasmas,based on which we will establish kinetic and magnetohydrodynamic models of intense-solid astrophysics plasmas in the framework of relativistic quantum theory,and study the propagation of linear waves in relativistic degenerate plasmas.The contributions of relativistic effects,Femi degeneracy pressure,and Bohm potential to the basic physical processes of intense-solid astrophysics plasmas will be discussed.We aim to reveal that the physical nature of intense-solid astrophysics plasmas is actually the relativistic quantum plasmas and make clear the real physical environment in which relativistic quantum plasmas.The paper is made up of two parts.Firstly,the propagation characteristics of linear waves in the quantum magnetoplasmas are investigated by using a non-relativistic quantum magnetohydrodynamic model,and the influence of quantum effects on the basic physical processes of plasmas is investigated.It is found that the quantum effects affect the propagation characteristics of electrostatic waves in the plasmas.For electromagnetic waves,the quantum effects only affect the dispersion relation of extraordinary waves perpendicular to the magnetic field,and do not affect the propagation characteristics of ordinary waves,Left-handed waves and Right-handed waves.Secondly,the relativistic quantum magnetohydrodynamics model based on covariant Wigner function is used to study the propagation characteristics of linear waves in intense-solid astrophysics plasmas.Results show that the corrections of both quantum effects and relativistic effects are significant when choosing the plasma parameters of the laser-based plasma compression schemes.This is a frontier project in plasmas physics,which provides an effective improvement in quantum plasmas field.This project also has a certain theoretical significance to the study of intense-solid astrophysics objets,such as white dwarf,pulsars and magnetars.
