论文摘要
我们回顾了在超导杂种结构（例如，Andreev干涉仪）中相结合热电效应的研究中的一些最新进展。我们阐明了这种系统中电子孔对称性破坏的多种机制，从而引起热电效应的显着增强。我们证明，依赖通量的热电器对应用的磁通$φ_x$的周期性依赖性在某些限制中可能会根据实验观察结果降低到$φ_x$的奇数甚至函数。我们还表明，可以通过应用温度梯度来控制和增强Andreev干涉仪中的DC Josephson电流，该温度梯度也可能导致非平凡的电流相关关系，并过渡到$π$键盘状态。
We review some recent advances in studies of phase-coherent thermoelectric effects in superconducting hybrid structures such as, e.g., Andreev interferometers. We elucidate a number of mechanisms of electron-hole symmetry breaking in such systems causing dramatic enhancement of thermoelectric effects. We demonstrate that the flux-dependent thermopower exhibits periodic dependence on the applied magnetic flux $Φ_x$ which in some limits may reduce to either odd or even functions of $Φ_x$ in accordance with experimental observations. We also show that dc Josephson current in Andreev interferometers can be controlled and enhanced by applying a temperature gradient which may also cause a nontrivial current-phase relation and a transition to a $π$-junction state.
