实验性二维玻璃成型机中颗粒和笼的动力学

Dynamics of particles and cages in an experimental 2D glass former

S. Mazoyer, F. Ebert, G. Maret, P. Keim

摘要:

我们调查的动态玻璃形成的二维胶体混合物,并显示存在的集体运动的颗粒。我们引入了一个均方位移MSD相对于最近的邻居,这表明显着的偏差,从通常的MSD量化我们的粒子的个别运动。结合对Van Hove函数自身部分的分析,这表明粒子与笼的耦合运动以及笼内跳跃过程。

英文摘要:

We investigate the dynamics of a glass forming 2D colloidal mixture and show the existence of collective motions of the particles. We introduce a mean square displacement MSD with respect to the nearest neighbors which shows remarkable deviations from the usual MSD quantifying the individual motion of our particles. Combined with the analysis of the self part of the Van Hove function this indicates a coupled motion of particles with their cage as well as intra cage hopping processes.
