原子与核物理学中的低能普适性

Low-Energy Universality in Atomic and Nuclear Physics

L. Platter

摘要:

为短程相互作用系统发展的有效场论可应用于大散射长度的冷原子系统和低能核子。因此,它是分析三体和四体系统中与Efimov效应相关的普适性质的理想工具。在这个“进度报告”中,我们将讨论在此框架内获得的最新结果,并报告有关包含高阶修正与有限范围的基本相互作用的进展。

英文摘要:

An effective field theory developed for systems interacting through short-range interactions can be applied to systems of cold atoms with a large scattering length and to nucleons at low energies. It is therefore the ideal tool to analyze the universal properties associated with the Efimov effect in three- and four-body systems. In this "progress report", we will discuss recent results obtained within this framework and report on progress regarding the inclusion of higher order corrections associated with the finite range of the underlying interaction.
