论文摘要
第3部分的第3部分来自硕士论文：用有效的场理论对紧凑对象进行建模。使用有效的现场理论框架进行扩展对象，我们构建了由重力理论组成的二元系统的有效理论，它是与电动力学的一般相对论，这些对象，这些对象，它们的质量，旋转，电荷及其有限大小的结构描述。我们在使用coset构造中得出的有效动作中的每个相关术语中获得了领先的订单，后者扩展到了，在这里，协变量的构建块以建立不变的操作员塔的构建块源自对称原则。在与文献中的理论系数相匹配之后，我们通过在旋转扩展对象以及带电的对象方面获得良好的牛顿后结果来展示我们理论的预测性。然后，我们为带电旋转的紧凑型物体的极化和耗散带来新的结果。
Part 2 of 3 from master's thesis: Modeling Compact Objects with Effective Field Theory. Using the Effective Field Theory framework for extended objects, we build the effective theory of a binary system made up of the most general compact objects in a theory of gravity as General Relativity with electrodynamics, objects which are described by their mass, spin, charge and their finite-size structure. We obtain the leading order post-Newtonian expansion to each of the relevant terms in the effective action that have been derived using the coset construction, where the covariant building blocks to build up the tower of invariant operators are derived from symmetry principles. Having matched the coefficients of the theory from the literature, we show the predictivity of our theory by obtaining well known post-Newtonian results on spinning extended objects, as well as on charged objects. Then, we bring new results on the polarizability and dissipation of charged spinning compact objects.
