论文摘要
我们使用量子点的谐振隧穿量子物理学提出了量子吸收冰箱。冷和热的储层是费米子的导线，通过量子点耦合到中央费米子腔，我们提出了配置，其中将热量从（非常热的）中央腔吸收到资源中，以选择性地从左侧的热储层转移到右上的冷藏储存中，从而选择性地传递热量。设备中的热传输是粒子 - 孔对称；我们发现冷却的两个方案是圆点能量的函数 - 相对于储层的费米能量对称 - 我们将它们与电子水平高于费米水平以上的电子和费米水平以下的孔相关联。我们还通过微调点的能量及其线宽来讨论优化冷却效果，并表征运输在热力学上可逆的机制，从而可以通过传递零冷却功率来实现性能的Carnot性能系数。
We propose a quantum absorption refrigerator using the quantum physics of resonant tunneling through quantum dots. The cold and hot reservoirs are fermionic leads, tunnel coupled via quantum dots to a central fermionic cavity, and we propose configurations in which the heat absorbed from the (very hot) central cavity is used as a resource to selectively transfer heat from the cold reservoir on the left, to the hot reservoir on the right. The heat transport in the device is particle---hole symmetric; we find two regimes of cooling as a function of the energy of the dots---symmetric with respect to the Fermi energy of the reservoirs---and we associate them to heat transfer by electrons above the Fermi level, and holes below the Fermi level, respectively. We also discuss optimizing the cooling effect by fine-tuning the energy of the dots as well as their linewidth, and characterize regimes where the transport is thermodynamically reversible such that Carnot Coefficent of Performance is achieved with zero cooling power delivered.
