Shell Model in the Complex Energy Plane

TL;DR

This paper reviews the complex-energy continuum shell model, which extends traditional shell models to describe bound states, resonances, and scattering states within an open quantum system framework.

Contribution

It introduces a comprehensive review of the complex-energy shell model, highlighting its foundations and applications in describing open quantum systems.

Findings

Provides a unified description of bound, resonant, and scattering states.

Extends the standard shell model to open quantum systems.

Facilitates accurate modeling of quasi-stationary states.

Abstract

This work reviews foundations and applications of the complex-energy continuum shell model that provides a consistent many-body description of bound states, resonances, and scattering states. The model can be considered a quasi-stationary open quantum system extension of the standard configuration interaction approach for well-bound (closed) systems.
