Combined few-body and mean-field model for nuclei

TL;DR

This paper introduces a novel combined few-body and mean-field model for nuclei, enabling a more comprehensive treatment of nuclear structure by integrating cluster correlations with mean-field approaches.

Contribution

The paper presents a new self-consistent method that merges cluster correlations with mean-field models, improving the description of nuclear properties and structures.

Findings

Effective description of dripline nuclei

Enhanced treatment of short- and large-distance properties

Potential applications to halos and Efimov states

Abstract

The challenging nuclear many-body problem is discussed along with classifications and qualitative descriptions of existing methods and models. We present detailed derivations of a new method where cluster correlations co-exist with an underlying mean-field described core-structure. The variation of an antisymmetrized product of cluster and core wave functions and a given nuclear interaction, provide sets of self-consistent equations of motion. After the applications on dripline nuclei we discuss perspectives with improvements and applications. In the conclusion we summarize while emphasizing the merits of consistently treating both short- and large-distance properties, few- and many-body correlations, ordinary nuclear structure, and concepts of halos and Efimov states.
