We propose an alternative segregation mechanism where the species-dependent interactions are dynamically induced by the phase synchronization of beads. Based on this scenario, we report an alternative segregation among beads of different restitution coefficients by molecular dynamics simulations. Since the beads are of equal size and mass, this is not related to the Brazilian-nut effect, nor can it be explained by the depletion force. Instead, this phenomenon derives from the phase synchronization, a concept which helps us determine the criteria for segregation and the phase boundaries that agree excellently with the simulation results.
我们提出了一种替代的分离机制，其中珠子的相位同步动态地诱导了物种依赖的相互作用。基于此情景，我们通过分子动力学模拟报告了不同恢复系数的珠子之间的另一种分离现象。由于珠子大小和质量相等，这与巴西坚果效应无关，也不能用耗尽力来解释。相反，这种现象源于相位同步，这一概念帮助我们确定分离标准和相界，其与模拟结果非常吻合。
