# Entanglement, identity and disentanglement in two-atom spontaneous emission

## TL;DR

This paper provides a theoretical analysis of two-atom spontaneous emission experiments, demonstrating that entanglement, exchange effects, and disentanglement by spontaneous emission collectively explain the observed phenomena, confirming disentanglement as a real process.

## Contribution

The paper offers a new theoretical framework that explains experimental results by integrating entanglement, exchange effects, and spontaneous emission-induced disentanglement.

## Key findings

- Experiments can be explained by combined effects of entanglement, exchange, and disentanglement.
- First verification of disentanglement by spontaneous emission.
- Theoretical analysis resolves conflicting interpretations of experimental data.

## Abstract

Two recent experiments studying the potential effect of entanglement on the emission properties of excited atoms produced in molecular photodissociation have been interpreted in conflicting ways. We present a theoretical analysis of the problem, showing that the experimental results can be explained by a combination of three processes: entanglement, exchange effects associated with the identical nature of the atoms and disentanglement by spontaneous emission. According to our approach these experiments provide the first verification of the phenomenon of disentanglement by spontaneous emission.
