从晶体到无序晶体：一个隐藏的有序-无序转变
From Crystals to Disordered Crystals: A Hidden Order-Disorder Transition
摘要：
我们发现了一个有序无序过渡从晶体到无序晶体的静态包装的无摩擦球。虽然几何指标大多是盲目的过渡，无序晶体已经表现出除了晶体的性质。过渡接近硬球的紧密堆积，从而导致紧密堆积点的奇异性。我们的证据表明，无序晶体的过渡和属性是共同决定的结构顺序和密度。在过渡附近，无序晶体的弹性模量和配位数显示出与晶体和堵塞固体不同的特定压力依赖性。
英文摘要：
We find an order-disorder transition from crystals to disordered crystals for static packings of frictionless spheres. While the geometric indicators are mostly blind to the transition, disordered crystals already exhibit properties apart from crystals. The transition approaches the close packing of hard spheres, giving rise to the singularity of the close packing point. We evidence that both the transition and properties of disordered crystals are jointly determined by the structural orders and density. Near the transition, the elastic moduli and coordination number of disordered crystals show particular pressure dependence distinct from both crystals and jammed solids.
