The hard sphere model is known to show a liquid-solid phase transition, with the solid expected to be either face centered cubic or hexagonal close packed. The differences in free energy of the two structures are very small and various attempts have been made to determine which structure is the more stable. We contrast the different approaches and extend one.
已知硬球模型会呈现液-固相变,其中固体预计为面心立方结构或六方密堆积结构。这两种结构的自由能差异非常小,人们已经进行了各种尝试来确定哪种结构更稳定。我们对比了不同的方法并扩展了其中一种方法。
