论文摘要
计算核相关函数所需的计算成本在夸克数量中增长，使得目前使用晶状体QCD对大型核的研究无法访问。但是，与许多这些相关函数相对应的张量表达式表现出高度的置换对称性，可以利用这些对称性来减少计算工作。我们使用两种用于计算核相关函数的新算法的插值操作员的某些选择提出了有希望的速度。
The computational cost required to calculate nuclear correlation functions grows factorially in the number of quarks, making the study of large nuclei inaccessible to ab initio study using lattice QCD at the present time. However, the tensor expressions corresponding to many of these correlation functions exhibit a high degree of permutation symmetry that can be exploited to reduce computational work. We present promising speed-ups for certain choices of interpolating operators using two new algorithms for computing nuclear correlation functions.
