论文摘要
多体的长距离相互作用系统可以在准平稳状态远距离地热力学平衡中保留。这些状态通常以一对反向传播密度簇或颗粒相空间中的单个非均匀核心 - 途径为特征。通过使用基于哈密顿均值场模型的粒子模拟，我们表明该模型支持具有多个簇或粒子孔的固定状态。我们还提出了一种基于波浪和波粒相互作用的机制，该机制导致这些簇的形成，并根据模拟的初始参数来表征这些新的准平台状态。
Many-body long-range interacting systems can remain approximately in a quasi-stationary state far-from-thermodynamic equilibrium. These states are typically characterized by a pair of counter-propagating density clusters, or by a single non-homogeneous core-halo in the phase-space of the particles. By using particle simulations based on the Hamiltonian mean-field model, we show that this model supports stationary states with multiple cluster or particle holes in phase-space density. We also propose a mechanism based on wave-wave and wave-particle interactions that lead to the formation of these clusters, and characterize these new quasi-stationary states in terms of the initial parameters of the simulations.
