9312723 Dufty Strongly coupled plasmas occur in a number of important astrophysical and terrestrial systems. The proposed research is a theoretical and numerical study of dynamical processes in the simplest case of a one-component, as seen through the probe of a single impurity atom or ion. The questions of interest are those beyond the domain of linear response and include important aspects of both radiative and transport phenomena. Among the phenomena to be studied are the emission, absorption and redistribution of radiation by the impurity, nonlinear stopping powers, and collision-time distributions. Theoretical techniques of non equilibrium statistical mechanics and stochastic processes will be closely correlated with computer simulations that ensure proper control of assumptions used in the theory. ***

9312723强耦合等离子体存在于许多重要的天体物理和陆地系统中。这项研究是对单组分最简单情况下的动力学过程的理论和数值研究，通过对单个杂质原子或离子的探测可以看出这一点。感兴趣的问题是那些超出线性响应领域的问题，包括辐射现象和传输现象的重要方面。需要研究的现象包括杂质对辐射的发射、吸收和再分配，非线性阻止能力和碰撞时间分布。非平衡统计力学和随机过程的理论技术将与计算机模拟密切相关，以确保对理论中使用的假设进行适当控制。***
