论文摘要
我们考虑由共享经典或量子相关性的本地平衡储层提供动力的热机。储层是由所谓的碰撞模型或重复相互作用模型建模的。在我们的框架中,最初以热状态制备的两个储层颗粒通过单一转化而相关,然后与形成工作流体的两个量子子系统进行局部相互作用。对于特定类别的单位者,我们展示了如何应用于储层颗粒的转换如何影响传递的热量和产生的工作。然后,当随机选择统一时,我们计算热量和工作的分布,证明总交换转换是最佳的。最后,我们根据机器的显微镜成分之间建立的经典和量子相关性分析了机器的性能。
We consider thermal machines powered by locally equilibrium reservoirs that share classical or quantum correlations. The reservoirs are modelled by the so-called collisional model or repeated interactions model. In our framework, two reservoir particles, initially prepared in a thermal state, are correlated through a unitary transformation and afterwards interact locally with the two quantum subsystems which form the working fluid. For a particular class of unitaries, we show how the transformation applied to the reservoir particles affects the amount of heat transferred and the work produced. We then compute the distribution of heat and work when the unitary is chosen randomly, proving that the total swap transformation is the optimal one. Finally, we analyse the performance of the machines in terms of classical and quantum correlations established among the microscopic constituents of the machine.
