TL;DR
This paper explores the application of time-dependent Green's functions to model the dynamics of nuclear reactions, starting with mean-field evolution in a simplified one-dimensional slab collision model.
Contribution
It introduces a Green's functions framework for nuclear reaction dynamics and discusses extending from mean-field to correlated many-body systems.
Findings
Mean-field evolution for colliding slabs demonstrated in 1D
Framework for extending to correlations outlined
Potential for applying Green's functions to complex nuclear reactions
Abstract
Nonequilibrium Green's functions represent underutilized means of studying the time evolution of quantum many-body systems. In view of a rising computer power, an effort is underway to apply the Green's functions formalism to the dynamics of central nuclear reactions. As the first step, mean-field evolution for the density matrix for colliding slabs is studied in one dimension. The strategy to extend the dynamics to correlations is described.
