Effective contact pairing forces from realistic calculations in infinite homogeneous nuclear matter
摘要:
非经验的有效接触配对力用于自洽平均场计算。这些对力,构造,以便准确地再现任何给定的微观配对间隙在无限均匀核物质的任何同位旋不对称性,给出了解析形式。作为一个副产品,这项工作提供了一个BCS间隙方程的解析解,可以应用于描述各种多体系统。
英文摘要:
Non-empirical effective contact pairing forces to be used in self-consistent mean-field calculations are presented. These pairing forces, constructed so as to reproduce exactly any given microscopic pairing gaps in infinite homogeneous nuclear matter for any isospin asymmetry, are given in analytical form. As a by-product, this work provides an analytical solution of the BCS gap equations which could be applied to describe various many-body systems.
