摘要:

由带负电荷的微米级颗粒悬浮在低压放电背景中形成的尘埃等离子体液体,由于其粒子间距小于毫米,时间尺度缓慢,是利用直接光学视频显微镜在动力学水平上研究一般时空动力学行为的良好候选者。本文从相互耦合和随机热扰动相互作用下的雪崩型粘滑合作跳跃过程的基本图象出发,简要回顾了我们最近对粒子微观运动及其结构重排的研究。并讨论了细观约束和外部慢剪切驱动的影响。

英文摘要:

The dusty plasma liquid formed by micro-meter sized particles negatively charged and suspended in a low pressure discharge background is a good candidate to study the generic spatio-temporal dynamical behaviors at the kinetic level through direct optical video-microscopy, because of the sub-mm interparticle spacing and the slow time scale. In this paper, starting from the basic picture of the avalanche type stick-slip cooperative hopping process under the interplay of mutual coupling and the stochastic thermal agitation, we briefly review our recent study on particle micro-motion and the associated structural rearrangement. The effect of mesoscopic confinement and external slow shear drive are also discussed.
