标题： Noise-induced breakdown of coherent collective motion in swarms

摘要： 我们考虑由具有吸引力长程相互作用的自推进粒子种群形成的群体。 这些群体代表多稳态动力系统，可以在相干运动状态或不存在整体平动运动的非相干振荡状态中存在。 随着噪声强度的增加，群体的相干运动状态被破坏，并发生突然过渡到振荡状态。 显示英文摘要

摘要： We consider swarms formed by populations of self-propelled particles with attractive long-range interactions. These swarms represent multistable dynamical systems and can be found either in coherent traveling states or in an incoherent oscillatory state where translational motion of the entire swarm is absent. Under increasing the noise intensity, the coherent traveling state of the swarms is destroyed and an abrupt transition to the oscillatory state takes place.
