An RPA program for jellium spheres

Abstract A FORTRAN 77 program is presented that calculates the electromagnetic response of small metal particles or atomic clusters. The program uses the random phase approximation and the local density approximation, and treats the clusters as jellium spheres. From the frequency-dependence response the polarizability, the plasmon resonance frequency, and the width of the resonance lines are directly extracted. Title of program: JELLYRPA Catalogue Id: ABTC_v1_0 Nature of problem The electromagnetic response of small metal particles and atomic clusters is an object of current experimental interest. The electric polarizability and the plasmon resonance are measured, among other properties. The quantum mechanical theory of the response in the many- electron system is still not fully developed, but the Random Phase Approximation (RPA) in the Local Density Approximation (LDA) is simple and accurate enough to serve as a theoretical baseline for more elaborate treatments.

摘要：
本研究提出一款FORTRAN 77程序，用于计算小型金属粒子或原子团簇的电磁响应。该程序采用随机相近似（Random Phase Approximation, RPA）与局域密度近似（Local Density Approximation, LDA），并将团簇建模为凝胶球。可从频率依赖的响应中直接提取极化率（polarizability）、等离激元共振（plasmon resonance）频率以及共振线宽。

程序名称：JELLYRPA
目录编号：ABTC_v1_0
问题概述：
小型金属粒子与原子团簇的电磁响应是当前实验研究的热点方向之一。除其他特性外，实验中常测量其电极化率与等离激元共振特性。多电子体系中电磁响应的量子力学理论尚未完全完善，但基于局域密度近似（LDA）下的随机相近似（RPA）方法简单且精度足够，可作为更复杂理论处理的理论基准。……
