摘要(中)

我們利用二維微粒電漿系統來研究二維庫倫液體中的集體激發微觀行為. 在微觀尺度下,液體展現異於巨觀中無序運動與結構. 微觀粒子在時間尺度小於熱平衡所需的時間時,展現了非高斯分布的位移分布. 其所對應的運動即是液體粒子開始要掙脫周圍粒子束傅, 而作出的de-caging運動. 我們針對此一運動來作其動力行為的研究, 尤其是它的尺度統計. 我們的研究顯示其尺度統計是符合一般非線性動力系統下常有的power law 關係. 此外,我們還探討邊界效應對二維庫倫團的運動的影響.

摘要(英)

Liquids, it is often thought that the strong stochastic thermal noise can
excite random motion and lead to a disordered structure.
Whether the micro-dynamics exhibits coherence in the time scale much shorter
than the thermal relaxation time is an open question.
From a more general view of modern nonlinear complex system, the liquid
system can be treated as a strongly coupled sub-excitable system perturbed
by noise.
Note that noise not only has the disruptive effect, but also provides the
constructive influence and induces the spatio-temporal coherence, especially
enhanced under the spatial coupling.
It is similar to the noise enhanced signal in the temporal system through
stochastic resonance.
In our glow discharge system, the suspended dust particles can be negatively
charged by the highly mobile electrons and turn them into the Coulomb crystal
or liquid state through their strong mutual Coulomb coupling.
The proper spatial and temporal scales offer an opportunity to directly
visualize the micro-structure and motions of this non-linear many-body system through video microscopy.
In this work, we study the micro-dynamics of the dust Coulomb liquid system,
which is less well explored due to its complicated disorder nature.
Besides, the experimental and numerical studies on effects from geometry
confinements are also discussed.
