Relativistic Electron-Photon Interactions in the Atomic Field

它的目的是对高能原子物理过程进行几个相关的研究，包括它们向更低能量的扩展。这包括研究具有相关原子结构的光子和电子的相互作用，包括在最终状态下有几个相互作用的连续粒子的情况。这些研究可以帮助理解相对论效应、延迟效应和更高的多极效应在可以与许多电子关联效应相媲美或主宰的情况下的作用，并有助于识别在高能下持续存在的关联效应的性质。具体的研究包括：考察原子过程的高能行为，这些行为在多大程度上遵循光子和电子相互作用的奇点，以及它们依赖于关联的程度；了解过程的其他全局特征，如解析性，以及作为结构信息替代品的零点的轨迹；澄清经典行为和量子行为之间的关系和转变；以及研究可观测性、分配和纠缠之间的关系。其他项目包括考虑在描述基本过程(如Delbruck散射和韧致辐射)以及描述原子过程(如光电离、瑞利和康普顿散射和韧致辐射)和它们所包含的独立原子信息方面的不足。

It is intended to undertake several related investigations into processes of high energy atomicphysics, including their extension toward lower energies. This involves studying the interactionsof photons and electrons with correlated atomic structures, including circumstances in whichthere are several interacting continuum particles in the final state. These studies can yieldunderstanding of the role of relativistic, retardation and higher multipole effects in regimeswhere they become comparable to or dominate the many electron correlation effects, and it canlead to an identification of the nature of the correlation effects which persist at high energies.Specific studies include: examining high energy behaviors of atomic processes, the extent towhich these behaviors follow from the singularities of photon and electron interactions, and theextent to which they depend on correlations; understanding other global features of processes,such as analyticity, also the trajectories of zeroes which serve as a surrogate for structuralinformation; clarifying the relations and transitions between classical and quantum behavior; andstudying the relationships among observables, partitioning, and entanglement. Other projectsinclude considerations of deficiencies in the description of basic processes, such as Delbruckscattering and bremsstrahlung, and characterization of atomic processes (such asphotoionization, Rayleigh and Compton scattering and bremsstrahlung) and the independentatomic information they contain.
