决定磁化等离子体中简并电子热导率和电导率的四个张量

Four tensors determining thermal and electric conductivities of degenerate electrons in magnetized plasma

G. S. Bisnovatyi-Kogan, M. V Glushikhina

摘要:

本文给出了具有强简并非相对论性电子和非简并核的磁化等离子体的玻尔兹曼方程的一个解。在不考虑电子-电子碰撞的Lorentz近似下,计算了非量子化磁场中扩散张量、热扩散张量和扩散热效应张量的分量,对强简并电子等离子体具有渐近精确性.首次得到了有磁场存在时电子扩散、热扩散和扩散热效应张量的渐近精确解析表达式。表达式揭示了一个相当复杂的依赖于磁场比类似的依赖于在以前的出版物中得出的这个问题。

英文摘要:

A solution to the Boltzmann equation is obtained for a magnetized plasma with strongly degenerate nonrelativistic electrons and nondegenerate nuclei. The components of the diffusion, thermal diffusion and diffusion thermoeffect tensors in a nonquantizing magnetic field are calculated in the Lorentz approximation without allowance for electron-electron collisions, which is asymptotically accurate for plasma with strongly degenerate electrons. Asymptotically accurate analytical expressions for the electron diffusion, thermal diffusion and diffusion thermoeffect tensors in the presence of a magnetic field are obtained for the first time. The expressions reveal a considerably more complicated dependence on magnetic field than analogous dependences derived in the previous publications on this subject.
