论文摘要
近年来，多体扰动理论在从头核结构理论的领域中遇到了文艺复兴。在各种应用中，表明扰动理论（包括新颖的风味）构成了描述原子核的有用工具，即作为一种成熟的多体方法，或者是一种支持更复杂的非扰动多体性方案的辅助方法。在这项工作中，讨论了多体扰动理论在核结构领域的当前状态，并提供了新的结果，以系统地研究中等质量的核作为有效而准确的（预处理）方法，以突出其功率。最终，使用多种体型扰动理论的几种最先进的口味对新一代的手性核哈密顿人进行了基准测试。
In recent years many-body perturbation theory encountered a renaissance in the field of ab initio nuclear structure theory. In various applications it was shown that perturbation theory, including novel flavors of it, constitutes a useful tool to describe atomic nuclei, either as a full-fledged many-body approach or as an auxiliary method to support more sophisticated non-perturbative many-body schemes. In this work the current status of many-body perturbation theory in the field of nuclear structure is discussed and novel results are provided that highlight its power as a efficient and yet accurate (pre-processing) approach to systematically investigate medium-mass nuclei. Eventually a new generation of chiral nuclear Hamiltonians is benchmarked using several state-of-the-art flavours of many-body perturbation theory.
