# Collective dynamics of accelerated atoms

## TL;DR

This paper investigates how accelerated atoms interact collectively with a quantum field, revealing entanglement and superradiance phenomena, and proposes an experimental setup using impurities in Bose-Einstein condensates.

## Contribution

It derives a general Hamiltonian for accelerated atoms interacting with a field and demonstrates its experimental feasibility with Bose-Einstein condensates.

## Key findings

- Entanglement arises from coherences between atoms.
- Superradiant emission is linked to collective dynamics.
- Experimental implementation with impurities in BECs is feasible.

## Abstract

We study the collective dynamics of accelerated atoms interacting with a massless field via an Unruh-deWitt-type interaction. We first derive a general Hamiltonian describing such a system and then, employing a Markovian master equation, we study the corresponding collective dynamics. In particular, we observe that the emergence of entanglement between two-level atoms is linked to the building up of coherences between them and to superradiant emission. In addition, we show that the derived Hamiltonian can be experimentally implemented by employing impurities in Bose-Einstein condensates.
