Particle and anti-particle bosonic entanglement in non-inertial frames

TL;DR

This paper investigates how entanglement between particle and antiparticle modes of a charged bosonic field behaves under acceleration, revealing differences from fermionic cases and showing entanglement can vanish at infinite acceleration.

Contribution

It provides the first analysis of bosonic entanglement redistribution between particle and antiparticle modes in non-inertial frames, highlighting key differences from fermionic fields.

Findings

Entanglement can vanish at infinite acceleration for bosonic fields.

Entanglement redistribution does not prevent entanglement loss in the infinite acceleration limit.

Contrasts with previous fermionic field results.

Abstract

We analyse the entanglement tradeoff between particle and anti-particle modes of a charged bosonic field between inertial and uniformly accelerated observers. In contrast with previous results for fermionic fields, we find that the entanglement redistribution between particle and antiparticle modes does not prevent the entanglement from vanishing in the infinite acceleration limit.
