论文摘要
已经进行了经典的分子动力学模拟（CMDS），以研究负责通过物质吸收辐射的一种主要机制之一，即BREMSSTRAHLUNG逆向。使用代码lammps使用200万个颗粒进行了200万$ z = 1 $的电离$ z = 1 $的两个组件等离子体（电子和离子）的CMD。一个参数化模型（具有6个可调常数），该模型涵盖了过去提出的大多数理论模型，以通过刺激的Bremsstrahlung刺激加热速率，作为与我们的模拟进行比较的参考。 CMDS的结果足够精确，可以排除过去模型的元素，例如仅取决于激光脉动$ω$而不是强度。已调整了参数化模型的6个常数，结果模型与我们的所有CMDS结果以及文献中先前的CMD的结果匹配。
Classical molecular-dynamics simulations (CMDS) have been conducted to investigate one of the main mechanism responsible for absorption of radiation by matter namely stimulated inverse bremsstrahlung. CMDS of two components plasmas (electrons and ions) for a large range of electron densities, electron temperatures, for ionization $Z=1$, were carried out with 2 million particles using the code LAMMPS. A parameterized model (with 6 adjustable constants), which encompasses most theoretical models proposed in the past to quantify heating rate by stimulated inverse bremsstrahlung, serves as a reference for comparison to our simulations. CMDS results are precise enough to rule out elements of these past models such as coulomb logarithms depending solely upon laser pulsation $ω$ and not upon intensity. The 6 constants of the parameterized model have been adjusted and the resulting model matches all our CMDS results and those of previous CMDS in the literature.
