论文摘要
核饱和度和对称能量是低能核物理学的关键特性，取决于核相互作用的细节。饱和度周围的状态方程也是推断出更高密度和中子恒星研究的重要锚点。在这里，我们开发了一个统一的统计框架，该统计框架使用逼真的核力量将有限核和无限核物质的理论建模联系起来。我们构建快速准确的仿真器，以可观察到可观察结果，并采用一种迭代历史匹配方法来探索和减少$Δ$ -Full手性相互作用的巨大参数域。我们执行严格的不确定性量化，并发现模型校准包括\ nuc {16} {o}可观察结果给出的饱和预测比仅使用少体数据的预测更精确。
Nuclear saturation and the symmetry energy are key properties of low-energy nuclear physics that depend on fine details of the nuclear interaction. The equation-of-state around saturation is also an important anchor for extrapolations to higher densities and studies of neutron stars. Here we develop a unified statistical framework that uses realistic nuclear forces to link the theoretical modeling of finite nuclei and infinite nuclear matter. We construct fast and accurate emulators for nuclear-matter observables and employ an iterative history-matching approach to explore and reduce the enormous parameter domain of $Δ$-full chiral interactions. We perform rigorous uncertainty quantification and find that model calibration including \nuc{16}{O} observables gives saturation predictions that are more precise than those that only use few-body data.
