核物理学在更广范围内的应用:从分子到恒星通过超核

Applications of nuclear physics to a wider context: from molecules to stars passing through hypernuclei

Lorenzo Fortunato

摘要:

在这篇文章中,我将回顾一些目前正在帕多瓦进行的研究(主要是在理论和强度项目中),重点是核理论在物理学其他几个分支中的跨学科应用,目的是展示核理论在意大利科学场景中的中心地位,以及这一肥沃领域在培育新物理学方面的突出地位。特别是,我将谈论:i)解决长期存在的“电子屏蔽难题”的最新解决方案,解决了地球上实验室实验结果与恒星中发生的核反应之间的核天体物理学基本争议;代数方法在非常不同的系统中的应用,例如:ii)超分子复合物H2@C60,即笼在富勒烯中的双原子氢分子,以及iii)超核的光谱,即由被捕获在(重)核中的λ粒子制成的系统。

英文摘要:

In this contribution I will review some of the researches that are currently being pursued in Padova (mainly within the In:Theory and Strength projects), focusing on the interdisciplinary applications of nuclear theory to several other branches of physics, with the aim of contributing to show the centrality of nuclear theory in the Italian scientific scenario and the prominence of this fertile field in fostering new physics. In particular, I will talk about: i) the recent solution of the long-standing "electron screening puzzle" that settles a fundamental controversy in nuclear astrophysics between the outcome of lab experiments on earth and nuclear reactions happening in stars; the application of algebraic methods to very diverse systems such as: ii) the supramolecular complex H2@C60, i.e. a diatomic hydrogen molecule caged in a fullerene and iii) to the spectrum of hypernuclei, i.e. systems made of a Lambda particles trapped in (heavy) nuclei.
