论文摘要
我们预测Weyl半金属网络中光子介导的异常热室效应(ATHE)。与需要外部磁场应用的磁光系统中的光子热大厅效应相反,韦尔半米金属网络中的Athe是这些系统的内在特性。由于Weyl半金属可以在广泛的光谱范围内的红外线表现出强烈的非偏射反应,因此与主要通量相比,这些系统中的热霍尔通量的大小可能相对较大。这是通过局部调整温度场的大小而不改变温度梯度的方向来对热通量进行定向控制的道路。
We predict an anomalous thermal Hall effect (ATHE) mediated by photons in networks of Weyl semi-metals. Contrary to the photon thermal Hall effect in magneto-optical systems which requires the application of an external magnetic field the ATHE in a Weyl semi-metals network is an intrinsic property of these systems. Since the Weyl semi-metals can exhibit a strong nonreciprocal response in the infrared over a broad spectral range the magnitude of thermal Hall flux in these systems can be relatively large compared to the primary flux. This ATHE paves the way for a directional control of heat flux by localy tuning the magnitude of temperature field without changing the direction of temperature gradient.
