在周期性边界条件下探索多尺度硬球的密度结构是数学和包括材料科学在内的许多学科的基本问题。在我们之前的研究[Koshoji和Ozaki，Phys. Rev. E 104，024 101（2021）]的基础上，我们对451个半径比和436种成分的densitrile sphere packings（DTSP）进行了详尽的计算探索。无偏探索的随机结构搜索方法发现不同的22个推定的DTSP，从而60个推定的DTSP被确定，包括38个DTSP讨论了以前的研究。一些已发现的DTSP是有序的，例如，（9-7-3）结构中的介质球被放置在一条直线上，包括晶胞，并且DTSP具有
The exploration of the densest structures of multi-sized hard spheres under periodic boundary conditions is a fundamental problem in mathematics and a wide variety of sciences including materials science. We present our exhaustive computational exploration of the densest ternary sphere packings (DTSPs) for 451 radius ratios and 436 compositions on top of our previous study [Koshoji and Ozaki, Phys. Rev. E 104, 024 101 (2021)]. The unbiased exploration by a random structure searching method discovers diverse 22 putative DTSPs, and thereby 60 putative DTSPs are identified in total including the 38 DTSPs discussed by the previous study. Some of the discovered DTSPs are well-ordered, for example, the medium spheres in the (9-7-3) structure are placed in a straight line with comprising the unit cell, and the DTSP has the
