Joint effects of entanglement and symmetrization: physical properties and exclusion

TL;DR

This paper investigates how entanglement and symmetrization jointly influence physical properties, specifically atomic absorption, revealing significant effects on absorption rates and identifying novel excluded states, with proposals for experimental testing.

Contribution

It introduces the combined impact of entanglement and symmetrization on physical properties and identifies new non-standard excluded states in multi-fermion systems.

Findings

Multi-particle superpositions significantly alter absorption rates.

Fermion dependence on overlap can be inhibited.

New non-standard excluded states emerge in multi-fermion superpositions.

Abstract

Entanglement and symmetrization lead to non-separable states that can modify physical properties. Using the example of atomic absorption we compare both types of effects when they are relevant at once. The presence of multi-particle superpositions largely alters the absorption rates of identical atoms, even inhibiting the dependence on overlapping for fermions. We also identify a set of non-standard excluded states related to multi-fermion superposition that naturally emerge in this context. We propose an arrangement based on the dissociation of molecules to test these ideas.
