The Quantum Electron Ground State in Laser Plasma at Low Temperature

本文利用量子统计理论中的 Wigner 矩阵方法对激光低温等离子体电子量子基态能量进行了计算,得到了量子基态能量的分析表达式。结果指出:因长程库仑相互作用而导致基态结构变化,同位相振动的电子是形成量子基态的主要原因,并指出激光等离子体中激光场和粒子相干振动对集团性离子反应的重要作用。

By means of Wigner matrix of quantum statistical theory, the electron ground state energy in laser plasma at low temperature has been calculated. The formula showing the energy is precisely obtained. It shows the change of structure of the ground state in the presence of long range Coulomb interactions. A significant part of the ground state energy comes from large groups of electrons oscillating in phase. Hence laser field and collective cohesion behavior of changed particles would be important in the reactions of ionized clusters.
