Effect of a quantum thermal machine on an entangled atomic system

In this contribution, we examine the effect of a quantum thermal machine on the behavior of two entangled atoms. It is shown that sudden changes (death/rebirth) in entanglement are predicted when increasing either the average rate of interaction coupling or the relative coupling. The maximum bounds of re-birthed entanglement decrease as machine parameters increase. Entanglement survival time can be increased as one reduces the average rate of interaction coupling. Due to the interaction, there will be an exchange of energies from the baths which may be a cool or hot flux. Therefore, the machine parameters can be used as controllers to switch between heating and refrigeration processes.
