Many-body interactions and nuclear structure

M. Hjorth-Jensen, D. J. Dean, G. Hagen, S. Kvaal

摘要:

本文提出了对核多体理论的几个挑战和我们对核物质稳定性的认识。为了实现这一点,我们提出了五种不同的情况下,从一个理想化的玩具模型。这些案例暴露了一些需要理解的问题,以便将核理论的最新进展与当前低能核物理的实验计划相匹配。特别是,我们专注于我们目前的理解,或缺乏,多体力,以及它们如何演变为粒子数量的函数。我们提供了理论和实验之间的差异的例子,并概述了未来的研究方向的一些选定的观点。

英文摘要:

This article presents several challenges to nuclear many-body theory and our understanding of the stability of nuclear matte r. In order to achieve this, we present five different cases, starting with an idealized toy model. These cases expose problems that need to be understood in order to match recent advances in nuclear theory with current experimental programs in low-energy nuclear physics. In particular, we focus on our current understanding, or lack thereof, of many-body forces, and how they evolve as functions of the number of particles . We provide examples of discrepancies between theory and experiment and outline some selected perspectives for future research directions.
