Quantum electrodynamics (QED) is a highly demanding subfield of theoretical physics: one faces both field theoretical as well as numerical difficulties and challenges. Typically, in order to advance theory from the current level of understanding and in order to organize a functioning work group in this domain, it is necessary to have postdoctoral support for the activities, because the demanding calculations depend on previously acquired knowledge either in field theory or in numerical studies, or preferably in both. Here, within a Heisenberg Fellow Junior Research Group located in Heidelberg, a proposal is offered which includes a support of the group activities by two postdoctoral scientists, to solve various topical problems of an increased level of difficulty, in both bound-state calculations as well as in other, application-oriented approaches that include the interaction of atoms with conducting surfaces.

量子电动力学（QED）是一个高度要求的理论物理学子场：一个人面临着场理论和数值困难和挑战。通常，为了使理论从当前的理解水平发展，为了在该领域中组织一个功能的工作组，有必要对活动进行博士后支持，因为苛刻的计算取决于现场理论或数值研究中的先前获得的知识，或者在两者中优选。在这里，在海德堡的一个少年研究小组中，提出了一项提案，其中包括两位博士后科学家对小组活动的支持，以解决在界限计算以及其他面向应用程序的方法中，包括与行为相互作用的相互作用的各种困难水平的主题问题。
