标题： $\textit{Ab initio}$ Exact Calculation of Strongly-Correlated Nucleonic Matter

摘要： 密集的核物质对于理解致密星体和推断向非约束夸克相的转变具有重要意义。我们展示了使用最先进的全组态相互作用量子蒙特卡罗（FCIQMC）方法对无限核物质的$\textit{ab initio}$精确计算，使我们能够严格基准多体方法并评估核物质强关联的程度。该方法已在小基组内通过数值验证与精确对角化一致。使用手征核力对核物质的计算表明，对称核物质的强关联程度比预期的要显著得多，这引发了对之前$\textit{ab initio}$核物质计算中截断方法的疑问，并为从第一性原理同时描述有限核和无限核物质提供了见解。 显示英文摘要

摘要： Dense nucleonic matter is of vital importance for understanding compact stars and inferring the transition into deconfined quark phase. We present the $\textit{ab initio}$ exact calculations of infinite nucleonic matter with the state-of-the-art full configuration-interaction quantum Monte Carlo (FCIQMC) method, enabling us to rigorously benchmark many-body methods and assess the degree to which the nucleonic matter is strongly correlated. This method has been numerically testified to exact diagonalization within a small basis. Calculations of nucleonic matter using the chiral nuclear forces reveal that the symmetric nuclear matter is strikingly strongly correlated than expected, raising questions on previous $\textit{ab initio}$ calculations of nuclear matter with truncations and offering insights into simultaneous descriptions of finite nuclei and infinite nucleonic matter from first principles.
