## TL;DR

This paper studies how entanglement between two circularly accelerated atoms evolves when interacting with electromagnetic vacuum fluctuations, revealing polarization-dependent effects and differences from uniform acceleration and thermal cases.

## Contribution

It introduces a detailed analysis of entanglement dynamics for circularly accelerated atoms with electromagnetic fields, highlighting polarization effects and contrasting with other acceleration scenarios.

## Key findings

- Entanglement decay rate is polarization-dependent.
- Circular acceleration leads to faster entanglement decay than uniform acceleration.
- Revival and enhancement of entanglement are less prominent in circular acceleration.

## Abstract

We investigate, in the framework of open quantum systems, the entanglement dynamics of two circularly accelerated two-level atoms with the same centripetal acceleration interacting with a bath of fluctuating electromagnetic fields in the Minkowski vacuum. We assume that the two atoms rotate synchronically with their separation perpendicular to the rotating plane, and study the entanglement degradation, creation, revival, and enhancement by solving the Markovian master equation. In contrast to the scalar-field case, the entanglement dynamics is crucially dependent on the atomic polarizations in the sense that the polarization directions may affect the entanglement decay rate, and may determine the occurrences of entanglement creation, revival and enhancement. Compared with the uniformly accelerated case and the thermal case, the decay rate of entanglement for circularly accelerated atoms is larger, while the revival and enhancement rates are smaller.
