We theoretically propose and numerically demonstrate a radiative thermal router based on magnetic Weyl semimetals. In designing the thermal router, we utilize two unique properties of optical gyrotropy in magnetic Weyl semimetals: great tunability and nanoscale inhomogeneity. The proposed thermal router consists of three spheres made of magnetic Weyl semimetals, one tunable and two fixed. It can direct a heat flow to a drain of choice by moving the Weyl nodes in the tunable magnetic Weyl semimetal using an external electric, magnetic, or optical field. Such a Weyl-semimetal-based radiative thermal router could enable exciting opportunities in energy harvesting and heat transfer applications.

基于可调谐磁Weyl半金属的辐射热路由器

我们从理论上提出并以数值论证了基于磁性Weyl半金属的辐射热路由器。在设计热router刨机时，我们利用磁性Weyl半金属的光学回旋性的两个独特特性：极大的可调谐性和纳米级的不均匀性。拟议中的热router刨机由三个由Weyl磁性半金属制成的球体组成，一个球体可调，两个球体固定。通过使用外部电场，磁场或光场移动可调谐磁性Weyl半金属中的Weyl节点，它可以将热流引导至选定的排放口。这种基于Weyl-半金属的辐射热路由器可以在能量收集和传热应用中带来令人兴奋的机遇。
