葡萄干布丁模型中的强筛选
Strong screening in the plum pudding model
摘要：
我们研究了一个广义的汤姆逊问题，出现在几个凝聚态的设置：相同的点电荷粒子可以渗透到一个均匀带电的球体内，与全球电中性。重点是在大库仑耦合的标度律，从平均场行为的偏差，结合蒙特卡罗模拟和分析处理内的准本地化的电荷近似，它提供了可靠的预测。我们还发现了由离子相关性驱动的局部过充电现象。
英文摘要：
We study a generalized Thomson problem that appears in several condensed matter settings: identical point-charge particles can penetrate inside a homogeneously charged sphere, with global electro-neutrality. The emphasis is on scaling laws at large Coulombic couplings, and deviations from mean-field behaviour, by a combination of Monte Carlo simulations and an analytical treatment within a quasi-localized charge approximation, which provides reliable predictions. We also uncover a local overcharging phenomenon driven by ionic correlations alone.
