论文摘要
我们提出了一种新的方法，通过依靠微波电子中常用的散射矩阵形式主义来解决电路中详细的平衡违规方法。这允许在高频下包含最重要的延迟效果。我们定义了相空间动量，传热和交叉功率的光谱密度，这可以作为详细侵犯平衡的标准。我们通过在空间和时间上的几个不同对称性的两个端口电路上的4-8 GHz频率范围的测量来确认我们的理论。这验证了我们的方法，这将允许在超低温度下处理量子电路。
We propose a new approach to detailed balance violation in electrical circuits by relying on the scattering matrix formalism commonly used in microwave electronics. This allows to include retardation effects which are paramount at high frequencies. We define the spectral densities of phase space angular momentum, heat transfer and cross power, which can serve as criteria for detailed balance violation. We confirm our theory with measurements in the 4-8 GHz frequency range on several two port circuits of varying symmetries, in space and time. This validates our approach, which will allow to treat quantum circuits at ultra-low temperature.
