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）是理论物理的一个要求很高的子领域：它面临着场理论和数值方面的困难和挑战。通常，为了从当前的理解水平推进理论，并为了在该领域组织一个有效的工作组，有必要为这些活动提供博士后支持，因为要求较高的计算取决于先前获得的领域理论或数值研究知识，或者最好是两者兼而有之。在这里，位于海德堡的海森堡研究员初级研究小组提出了一项提案，其中包括两名博士后科学家对小组活动的支持，以解决束缚态计算以及其他面向应用的方法（包括原子与导电表面的相互作用）中难度增加的各种主题问题。
