我们在现实光子电路中以数值方式实现了热辐射泵的概念，并证明了它们控制两个温度相同的储层之间发出的辐射电流的效率。所提出的泵浦方案涉及控制光子电路光谱特性的两个参数的循环绝热调制。我们表明，当系统的循环调制被正确设计为接近光子电路参数空间中的谐振简并时，所得到的泵浦循环表现出最大辐射电流。开发的 Floquet 散射框架在绝热极限下可归结为瞬时散射矩阵的分析，为设计和预测此类热泵的性能提供了工程工具。我们的预测通过绝热驱动光子腔的时域模拟得到证实。
We numerically implement the concept of thermal radiation pumps in realistic photonic circuits and demonstrate their efficiency to control the radiation current, emitted between two reservoirs with equal temperature. The proposed pumping scheme involves a cyclic adiabatic modulation of two parameters that control the spectral characteristics of the photonic circuit. We show that the resulting pumping cycle exhibits maximum radiation current when a cyclic modulation of the system is properly engineered to be in the proximity of a resonance degeneracy in the parameter space of the photonic circuit. A developed Floquet scattering framework, which in the adiabatic limit boils down to the analysis of an instantaneous scattering matrix, is offering an engineering tool for designing and predicting the performance of such thermal pumps. Our predictions are confirmed by time-domain simulations invoking an adiabatically driven photonic cavity.
