在球形约束势场中，三维强耦合带电粒子呈嵌套壳结构排列。通过实验、计算机模拟和理论分析，探讨了它们的结构特性对粒子间力类型的敏感性。虽然归一化的壳半径被发现是独立的屏蔽，壳占用数是敏感的屏蔽和定量解释的各向同性汤川模型。
Small three-dimensional strongly coupled charged particles in a spherical confinement potential arrange themselves in a nested shell structure. By means of experiments, computer simulations, and theoretical analysis, the sensitivity of their structural properties to the type of interparticle forces is explored. While the normalized shell radii are found to be independent of shielding, the shell occupation numbers are sensitive to screening and are quantitatively explained by an isotropic Yukawa model.
