用于物态方程计算的稠密等离子体原子结构模型

A model of dense-plasma atomic structure for equation-of-state calculations

Jean-Christophe Pain

摘要:

本文提出了一个基于超组态近似的稠密等离子体模型。在每个超组态中,原子核都被维格纳-塞茨球(电离层模型)中的电子完全屏蔽。相同电荷的超组态被分组为离子。它示出的波函数的边界值起着至关重要的作用的维里定理的形式,从压力公式推导。最后,提出并讨论了当束缚电子被量子力学处理而自由电子被准经典处理时,使电离层模型发生变化的条件。

英文摘要:

A model of dense plasmas relying on the superconfiguration approximation is presented. In each superconfiguration the nucleus is totally screened by the electrons in a Wigner-Seitz sphere (ion-sphere model). Superconfigurations of the same charge are grouped into ions. It is shown that boundary values of the wavefunctions play a crucial role in the form of the Virial theorem from which the pressure formula is derived. Finally, a condition is presented and discussed, which makes the ion-sphere model variational when bound electrons are treated quantum-mechanically and free electrons quasi-classically.
