Towards Quantum Transport for Nuclear Reactions

TL;DR

This paper explores the use of nonequilibrium Green's functions in modeling nuclear reactions, questioning whether all their information is necessary, through mean-field simulations of one-dimensional slab collisions.

Contribution

It investigates the relevance of the full Green's functions information in nuclear reaction modeling using mean-field approximations.

Findings

Green's functions contain more information than needed for certain nuclear reaction descriptions.

Mean-field calculations can effectively model slab collisions in one dimension.

The study suggests potential simplifications in quantum transport simulations.

Abstract

Nonequilibrium Green's functions represent a promising tool for describing central nuclear reactions. Even at the single-particle level, though, the Green's functions contain more information that computers may handle in the foreseeable future. In this study, we investigate whether all the information contained in the Green's functions is necessarily relevant when describing the time evolution of nuclear reactions. For this, we carry out mean-field calculations of slab collisions in one dimension.
