论文摘要
在本文中，我们使用单摩梅通路积分蒙特卡洛方法继续研究了均匀的电子气体，并研究了动量分布函数，并在温暖的密集物质方向上研究了对的相关功能。我们发现，如果非理想性在退化和非脱位病例中都足够强大，则单粒子动量分布函数偏离了费米分布并形成所谓的“量子尾巴”。这种效果始终在配对分布函数上出现短距离顺序，并且可以通过隧道通过围绕电子的有效潜在井来解释。另外，我们还计算了广泛范围的平均动力学和势能，从而大大扩展了我们先前的结果。
In this paper we continued our research of the uniform electron gas, using the single--momentum path integral Monte Carlo method, and studied the momentum distribution functions and the pair correlation functions in the warm dense matter regime. We discovered that the single--particle momentum distribution function deviates from the Fermi distribution and forms so-called "quantum tails" at high momenta, if non-ideality is strong enough in both degenerate and non-degenerate cases. This effect is always followed by the appearance of the short--range order on the pair distribution functions and can be explained via the tunneling through the effective potential wells surrounding the electrons. Also we calculated the average kinetic and potential energies in the wide range of states, expanding our previous results significantly.
