论文摘要
我们重新审视了一个描述Seebeck对两个电荷围绕电路之间弱连接的效果的模型，该电路在[Phys]中已提出。 Rev. B 97，085403（2018）]。假设量子点接触的反射幅度较小，我们在扰动理论中计算热电系数。在三种不同的情况下，我们专注于热电导的线性响应方程，例如：费米液体与费米液体，费米液体与非富特液体，非Furmi液体与非Fermi液体。在费米液体和非Fermi液体状态下，分析了热电导的振荡与每个量子点的栅极电压的函数。我们讨论了该模型的可能实现实现，以观察热电导测量中非FERMI液体行为的特征。
We revisit a model describing Seebeck effect on a weak link between two charge Kondo circuits, which has been proposed in the [Phys. Rev. B 97, 085403 (2018)]. We calculate the thermoelectric coefficients in the perturbation theory assuming smallness of the reflection amplitudes of the quantum point contacts. We focus on the linear response equations for the heat conductance in three different scenarios as: Fermi liquid vs Fermi liquid, Fermi liquid vs non-Fermi liquid, nonFermi liquid vs non-Fermi liquid. The oscillations of the heat conductance as a function of the gate voltage of each quantum dot are analysed in both Fermi liquid and non-Fermi liquid regimes. We discuss possible experimental realizations of the model to observe the signatures of the non-Fermi liquid behaviour in the heat conductance measurements.
