论文摘要
我们研究了由两个谐波振荡器之间的两级系统组成的组装的热传输，该系统由量子兔模型描述为使用可控的多层系统的纳米级热器件的原型。使用非相互作用 - 瓶近似（NIBA），我们发现线性热电导显示具有两峰结构的特征温度依赖性。我们还表明，热传输对模型参数敏感，用于弱系统浴耦合和两级系统与谐波振荡器之间的强杂交。多层系统的这种性质特征对于诸如热晶体管等应用是有利的，并且可以在超导电路中检查。
We investigate heat transport through an assembly consisting of a two-level system coupled between two harmonic oscillators, which is described by the quantum Rabi model, as a prototype of nanoscale heat devices using controllable multi-level systems. Using the noninteracting-blip approximation (NIBA), we find that the linear thermal conductance shows a characteristic temperature dependence with a two-peak structure. We also show that heat transport is sensitive to model parameters for weak system-bath coupling and strong hybridization between the two-level system and the harmonic oscillators. This property characteristic of the multi-level system is advantageous for applications such as a heat transistor, and can be examined in superconducting circuits.
