手性活性粒子的同步跃迁
Transition to synchrony in chiral active particles
摘要：
我研究二维手性活性粒子的确定性动力学。粒子被认为是与弹性排斥力相互作用的圆盘。从随机初始条件开始的粒子系综表明了导致其正常扩散的混沌碰撞。这种混乱是短暂的，因为一个同步的无碰撞状态突然建立起来。混沌的寿命随着粒子的数量呈指数增长。外部强迫（周期或混沌），以促进同步过渡。
英文摘要：
I study deterministic dynamics of chiral active particles in two dimensions. Particles are considered as discs interacting with elastic repulsive forces. An ensemble of particles, started from random initial conditions, demonstrates chaotic collisions resulting in their normal diffusion. This chaos is transient, as rather abruptly a synchronous collisionless state establishes. The life time of chaos grows exponentially with the number of particles. External forcing (periodic or chaotic) is shown to facilitate the synchronization transition.
