论文摘要
纯中子物质中的自旋敏感性是从辅助场扩散蒙特卡洛计算中计算出的。对不同的自旋不对称进行计算，同时使用扭曲平均边界条件来减少有限尺寸的效果。所采用的核相互作用包括现象学AV8 $^\ prime $+UIX的潜力和局部相互作用，这些相互作用源自手性有效的田间理论，直到近代到领先的顺序。
The spin susceptibility in pure neutron matter is computed from auxiliary field diffusion Monte Carlo calculations over a wide range of densities. The calculations are performed for different spin asymmetries, while using twist-averaged boundary conditions to reduce finite-size effects. The employed nuclear interactions include both the phenomenological Argonne AV8$^\prime$+UIX potential and local interactions that are derived from chiral effective field theory up to next-to-next-to-leading order.
