标题： Numerical Convergence of Electromagnetic Responses with the Finite-Amplitude Method

摘要： 原子核对电磁探针的响应是模拟光吸收或光去激发过程的关键量。 对于整个质量表的大规模计算，这种响应可以通过线性响应理论来估算。 由于有限振幅法（FAM）的引入，计算效率很高。 本文详细研究了作为控制理论数值实现的参数函数的响应函数的FAM计算的收敛性。 我们表明，与其他Hartree-Fock-Bogoliubov计算相比，响应对单粒子基底的细节不那么敏感。 显示英文摘要

摘要： The response of a nucleus to an electromagnetic probe is a key quantity to simulate photabsorption or photodeexcitation processes. For large calculations at the scale of the entire mass table, this response can be estimated by linear response theory. Thanks to the introduction of the finite-amplitude method (FAM), calculations are computationally efficient. In this paper, we investigate in more details the convergence of FAM calculations of the response function as a function of the parameters controlling the numerical implementation of the theory. We show that the response is much less sensitive to the details of the single-particle basis than, e.g., Hartree-Fock-Bogoliubov calculations.
