强耦合约束电荷的壳结构

Shell Structure of Confined Charges at Strong Coupling

J. Wrighton, J. W. Dufty, M. Bonitz, H. Kählert

摘要:

在$Γ$ = 50和100的强耦合条件下,对谐波阱中带电粒子壳层结构进行了理论描述。该理论是基于超网链近似的限制系统加上相关的桥函数的唯象表示的扩展。预测相比,相应的蒙特卡罗模拟和定量协议的径向密度分布。

英文摘要:

A theoretical description of shell structure for charged particles in a harmonic trap is explored at strong coupling conditions of $Γ$ = 50 and 100. The theory is based on an extension of the hypernetted chain approximation to confined systems plus a phenomenological representation of associated bridge functions. Predictions are compared to corresponding Monte Carlo simulations and quantitative agreement for the radial density profile is obtained.
