The language of modern physics is formulated in terms of the concept of fields. Our current comprehension of Nature on its fundamental level is based on dynamical field theories such as Einstein’s theory of general relativity for gravitational aspects and quantum field theories for the description of matter and their quantized interactions. Whereas both theory concepts have their origins in the reductionist search for the elements of space, time and matter, current theoretical research instead faces the challenge of complexity: a variety of physical properties emerge in a fascinating manner from the interplay of matter and fields. The core research idea of this Research Training Group (RTG) is to investigate, understand and compute the emergence of complexity in gravitational and quantum field theories starting from their foundations. We focus on a set of examples of physical topicality or conceptual relevance, such as gravitational wave phenomena and black holes on the gravity side, and dynamics and criticality near phase transitions on the quantum side. Of particular interest is the interface of gravitational and quantum theories, where our understanding profits substantially from the cross-correlations among these fields both conceptually and from the method side.As such, each topic goes along with the development of theoretical and computational techniques in order to extend the toolbox of the scientific method. Rising up to the challenge posed by quantitative theoretical physics is an integral part of this RTG. The qualification program and supervision strategy of the RTG is fully research oriented and is based on the principles of academic freedom, competition and internationalization. Conducting successful research at the forefront of modern theoretical physics requires a highly specialized training. A solid long-term career perspective, on the other hand, necessitates also a broad basis of knowledge and competences. Both objectives will be supported by a Curriculum with local and joint elements and an internationalized research-oriented training.Important added values for training and supervision arising from the joint RTG Jena/Leipzig are: the advanced part of the Curriculum is significantly broadened; research topics complement each other, yielding a larger overall coherence; the PhD fellows form a larger transregional peer group stimulating motivation, research enthusiasm, and orientation towards competitiveness.

现代物理学的语言是根据场的概念来表述的。我们目前对自然的基本理解是基于动力学场论，如爱因斯坦的广义相对论的引力方面和量子场论的描述物质和它们的量子化相互作用。虽然这两个理论概念都起源于对空间、时间和物质元素的还原论探索，但当前的理论研究却面临着复杂性的挑战：各种物理性质以一种迷人的方式从物质和场的相互作用中出现。该研究培训小组（RTG）的核心研究思想是从基础开始调查，理解和计算引力和量子场论中复杂性的出现。我们专注于一组物理话题性或概念相关性的例子，如引力波现象和引力方面的黑洞，以及量子方面相变附近的动力学和临界性。特别令人感兴趣的是引力和量子理论的接口，我们的理解从这些领域之间的相互关联中获益匪浅，无论是从概念上还是从方法上。因此，每个主题都沿着理论和计算技术的发展，以扩展科学方法的工具箱。上升到定量理论物理所带来的挑战是这个RTG的一个组成部分。RTG的资格计划和监督策略完全以研究为导向，并基于学术自由，竞争和国际化的原则。在现代理论物理学的前沿进行成功的研究需要高度专业化的培训。另一方面，一个坚实的长期职业前景也需要广泛的知识和能力基础。这两个目标都将得到一个具有地方和联合要素的课程和一个国际化的以研究为导向的培训的支持。耶拿/莱比锡联合RTG产生的培训和监督的重要附加值是：课程的高级部分大大拓宽;研究课题相互补充，产生更大的整体一致性;博士研究员形成了一个更大的跨区域的同行群体，激发了动力，研究热情和竞争力的方向。
