摘要

预测了非互易系统中光子自旋角动量梯度引起的横向辐射热流。在空间可变外磁场作用下，分析了C4对称磁光网络中逆自旋霍尔效应的热模拟。这一发现通过光的自旋角动量的局部和动态控制，为非互易系统的热管理和能量转换开辟了新的途径。

Inverse Spin Thermal Hall Effect in Nonreciprocal Photonic Systems.

A transverse radiative heat flux induced by the gradient of spin angular momentum of photons in nonreciprocal systems is predicted. This thermal analog of the inverse spin Hall effect is analyzed in magneto-optical networks exhibiting C4 symmetry, under the action of spatially variable external magnetic fields. This finding opens new avenues for thermal management and energy conversion with nonreciprocal systems through a localized and dynamic control of the spin angular momentum of light.
