摘要

在这篇论文中，我们研究了量子热机对两个纠缠原子行为的影响。研究表明，当相互作用耦合的平均速率或相对耦合增加时，纠缠的突然变化（死亡/重生）是可以预测的。随着机器参数的增加，重生纠缠的最大边界会减小。随着交互耦合平均速率的降低，纠缠存活时间也会增加。由于相互作用，浴槽会产生能量交换，这可能是冷通量，也可能是热通量。因此，机器参数可用作控制器，在加热和制冷过程之间进行切换。

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.
