论文摘要
我们研究了热循环器，其中三个铅是正常或超导的三个导线。一个磁场以及可能的超导相，可以控制三个不同温度偏见的接触之间的热流的优先方向。这项研究的主要目的是分析非理想设备中热循环的要求，特别是集中于样本 - 样本变化。通常，我们发现设备的循环性能是好的，只要仅涉及几个传输渠道即可。我们将具有正常接触的循环器与具有超导接触的循环器的性能进行了比较，并发现循环系数基本上没有变化。
We investigate heat circulators where a phase coherent region is contacted by three leads that are either normal- or superconducting. A magnetic field, and potentially the superconducting phases, allow to control the preferential direction of the heat flow between the three-different temperature-biased contacts. The main goal of this study is to analyze the requirements for heat circulation in non-ideal devices, in particular focusing on sample-to-sample variations. Quite generally, we find that the circulation performance of the devices is good as long as only a few transport channels are involved. We compare the performance of circulators with normalconducting contacts to those with superconducting contacts and find that the circulation coefficient are essentially unchanged.
