Dynamical Properties of Strongly Coupled Plasmas (Physics)

利用带电杂质作为探针，对强耦合等离子体中的动力学过程进行了理论研究。等离子体是通过它在杂质处的总电场来表征的，而不是通过粒子轨迹和截面来表征。该公式更适合于强耦合，并且侧重于线性响应以外的电场动力学。这项研究的第一部分涉及研究高电荷态离子在单组分等离子体中的辐射和输运性质，开发电场动力学描述，并将其应用于线形的诊断。研究的第二部分涉及电子扩散的研究，旨在提供对最近发现的局域化-离域化转变的理解。

A theoretical study will be performed of dynamical processes in strongly coupled plasmas using a charged impurity as a probe. The plasma is characterized through its total electric field at the impurity, rather than through particle trajectories and cross-sections. The formulation is more appropriate for strong coupling and focuses on electric field dynamics beyond linear responses. The first part of the research involves a study of radiative and transport properties of a highly charged ion in a one component plasma, developing descriptions of electric field dynamics with applications to line shapes as a diagnostic. The second part of the research involves a study of electron diffusion, intended to provide understanding of a recently discovered localization-delocalization transition.
