Newton's third law—the action-reaction symmetry—can be violated for effective interbody forces in open and nonequilibrium systems that are ubiquitous in areas as diverse as complex plasmas, colloidal suspensions, active and living soft matter, and social behavior. While studying monolayer complex plasma (confined charged particles in an ionized gas) with nonreciprocal interactions mediated by plasma flows, in silico we found that an interplay between melting and thermal activation drastically transforms the collective dynamics: the order-disorder transition modifies the system's thermal steady state so that the crystal tends to melt, whereas the fluid tends to freeze, jumping chaotically between the two states. We identified this collective chaotic behavior as strange attractors formed in a monolayer complex plasma and link the strange attractor behavior to the specifics of interparticle interactions.

在具有不可逆的有效相互作用的系统中融化引起的奇怪吸引子。

牛顿的第三定律-行为-反应对称性-在开放和非平衡系统中的有效的体间力可能会受到违反，而该系统在复杂的血浆，胶体悬浮液，活性和活性软物质以及社会行为等广泛的领域中普遍存在。在研究单层复合等离子体（电离气体中的带电带电粒子）以及等离子体流介导的不可逆相互作用时，在计算机上我们发现，熔化和热活化之间的相互作用极大地改变了集体动力学：有序-无序转变改变了系统的热稳态，从而晶体趋于熔化，而流体趋于冻结，在这两种状态之间混沌地跳跃。我们将这种集体混沌行为识别为在单层复合等离子体中形成的奇怪吸引子，并将该奇怪吸引子行为与粒子间相互作用的细节联系起来。
