由无限物质性质导出的扩展Skyrme赝势
Extended Skyrme pseudo-potential deduced from infinite matter properties
摘要：
讨论了N $\ell$ LO Skyrme赝势（$\ell$ = 2，3）对物态方程的贡献.我们表明，通过添加第四和第六阶梯度项，它是可能的，公平地再现自旋/同位旋分解的状态方程从\emph{ab-initio}方法。此外，通过检查状态方程的分波分解，我们第一次展示了一种可能的方式来添加明确的限制的Skyrme相互作用的张量项的符号。
英文摘要：
We discuss the contributions to the Equation of State for the N$\ell$LO Skyrme pseudo-potential ($\ell$=2,3). We show that by adding 4th and 6th order gradient terms, it is possible to fairly reproduce the spin/isospin decomposition of an equation of state obtained from \emph{ab-initio} methods. Moreover, by inspecting the partial-wave decomposition of the equation of state, we show for the first time a possible way to add explicit constraints on the sign of the tensor terms of the Skyrme interaction.
