中子星星观测的最新进展有可能限制极端密度和温度下强相互作用物质的性质，否则很难通过直接实验研究获得。与此同时，手征有效场论已经发展成为一个强大的理论框架，研究核相互作用和核物质的性质与量化的不确定性，在天体物理学的兴趣为中子星建模的制度。在这篇文章中，我们回顾了手征有效场论方法来构建微观核力的最新进展，并重点介绍了多体微扰理论作为计算热致密核物质的结构，相位和线性响应特性的计算有效工具。我们还展示了如何有效的场论与贝叶斯方法相结合，使核理论预测，核实验和核状态方程的观测约束之间的统计上有意义的比较。1 ar X iv：2 10 1. 01 70 9v 1 [ nu cl -t h] 5 J an 2 02 1
Recent advances in neutron star observations have the potential to constrain the properties of strongly interacting matter at extreme densities and temperatures that are otherwise difficult to access through direct experimental investigation. At the same time, chiral effective field theory has developed into a powerful theoretical framework to study nuclear interactions and nuclear matter properties with quantified uncertainties in the regime of astrophysical interest for modeling neutron stars. In this article, we review recent developments in the chiral effective field theory approach to constructing microscopic nuclear forces and focus on many-body perturbation theory as a computationally efficient tool for calculating the structure, phases, and linear-response properties of hot and dense nuclear matter. We also demonstrate how effective field theory combined with Bayesian methods enables statistically meaningful comparisons between nuclear theory predictions, nuclear experiments, and observational constraints on the nuclear equation of state. 1 ar X iv :2 10 1. 01 70 9v 1 [ nu cl -t h] 5 J an 2 02 1
