GRK 2522: Strong Dynamics and Criticality in Quantum and Gravitational Systems

现代物理学的语言是用场的概念来表述的。我们目前对自然的基本理解是建立在动力学场论的基础上的，比如爱因斯坦关于引力方面的广义相对论和描述物质及其量子化相互作用的量子场论。尽管这两种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：从物质和场的相互作用中，以一种迷人的方式出现了各种物理特性。本研究训练组（RTG）的核心研究思路是从引力和量子场论的基础出发，研究、理解和计算复杂性的产生。我们专注于一系列物理话题性或概念相关性的例子，例如重力方面的引力波现象和黑洞，以及量子方面的相变附近的动力学和临界性。特别有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得了很大的好处，无论是从概念上还是从方法上。因此，每个主题都伴随着理论和计算技术的发展，以扩展科学方法的工具箱。迎接定量理论物理提出的挑战是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，以学术自由、竞争和国际化为原则。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训练。另一方面，扎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具有地方和联合成分的课程以及国际化的研究型培训的支持。耶拿/莱比锡联合RTG对培训和监督产生的重要附加价值是：课程的高级部分大大扩大；研究课题相辅相成，整体连贯性更强；博士生形成了一个更大的跨地区同行群体，激发了研究动机、研究热情和竞争导向。

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.
