Entanglement of arbitrary spin fields in non-inertial frames

TL;DR

This paper extends the analysis of quantum entanglement in non-inertial frames to fields of arbitrary spin, including electromagnetic and Rarita-Schwinger fields, revealing that at infinite acceleration, spin differences become negligible.

Contribution

It generalizes previous entanglement studies to arbitrary spin fields and beyond the single mode approximation, providing new insights into spin-dependent entanglement behavior.

Findings

No significant differences in entanglement at infinite acceleration across different spins

Extended analysis to fields of arbitrary spin beyond previous single mode approximations

Specific examination of electromagnetic and Rarita-Schwinger fields in non-inertial frames

Abstract

We generalise the study of fermionic and bosonic entanglement in non-inertial frames to fields of arbitrary spin and beyond the single mode approximation. After the general analysis we particularise for two interesting cases: entanglement between an inertial and an accelerated observer for massless fields of spin 1 (electromagnetic) and 3/2 (Rarita-Schwinger). We show that in the limit of infinite acceleration, no significant differences appear between the different spin fields for the states considered.
