摘要: 同时考虑分子的平动与转动自由度,用等温等压系综的路径积分蒙特卡罗方法研究了固体氢的状态方程。在有实验数据的区域,计算结果同实验结果符合很好,在无实验数据的超高压区域,计算结果同实验的外推结果符合。为了定量研究零点运动,还计算了体系的能量。

Abstract: The path integral Monte Carlo method with a constant pressure ensemble is used to study the equation of state of solid hydrogen with translational and rotational degrees of freedom. The results are in quantitative agreement with the experimental data. For understanding the quantum nature of the solid, the energies of the system at different temperatures are also calculated.-
