强关联等离子体介质的热力学性质和电导率
Thermodynamic properties and electrical conductivity of strongly correlated plasma media
摘要:
本文采用经典反应蒙特卡罗(REMC)、直接路径积分蒙特卡罗(PIMC)和量子力学Wigner表象中的量子动力学方法研究了稠密氢和氘的热力学性质和电导率。我们报道了氘压缩准等熵的计算结果,与实验符合得很好。我们还求解了稠密简并氢的Wigner-Liouville方程,用PIMC方法计算了初始平衡态。得到的粒子轨迹确定的动量-动量关联函数和电导率,并与现有的理论和模拟进行比较。
英文摘要:
We study thermodynamic properties and the electrical conductivity of dense hydrogen and deuterium using three methods: classical reactive Monte Carlo (REMC), direct path integral Monte Carlo (PIMC) and a quantum dynamics method in the Wigner representation of quantum mechanics. We report the calculation of the deuterium compression quasi-isentrope in good agreement with experiments. We also solve the Wigner-Liouville equation of dense degenerate hydrogen calculating the initial equilibrium state by the PIMC method. The obtained particle trajectories determine the momentum-momentum correlation functions and the electrical conductivity and are compared with available theories and simulations.
