论文摘要
当嵌入在N-S的两端设置中时，我们提出并理论上研究了弹道Aharonov-Bohm（AB）环的行为，该设置由正常金属（N）和超导（S）铅组成。该设备基于可用的当前技术，我们在这项工作中表明，它构成了有希望的混合量子热器件，作为量子热发动机和量子热整流器。值得注意的是，我们证明了在AB环和结构的超导特性中单粒子量子干扰的相互作用，以实现该量子设备的混合工作模式。它作为量子加热发动机的效率达到了Carnot效率的$ 55 \％$，并且我们预测获得$ 350 \％$的热整流因子。这些预测使得该设备对于将来的相位量热纳米台词的高度有希望。
We propose and theoretically investigate the behavior of a ballistic Aharonov-Bohm (AB) ring when embedded in a N-S two-terminal setup, consisting of a normal metal (N) and superconducting (S) leads. This device is based on available current technologie and we show in this work that it constitutes a promising hybrid quantum thermal device, as quantum heat engine and quantum thermal rectifier. Remarkably, we evidence the interplay of single-particle quantum interferences in the AB ring and of the superconducting properties of the structure to achieve the hybrid operating mode for this quantum device. Its efficiency as a quantum heat engine reaches $55\%$ of the Carnot efficiency, and we predict thermal rectification factor attaining $350\%$. These predictions make this device highly promising for future phase-coherent caloritronic nanodevices.
