Due to the large anomalous Hall effect, magnetic Weyl semimetals can support nonreciprocal surface plasmon polariton modes in the absence of an external magnetic field. This implies that magnetic Weyl semimetals can find novel application in (thermal) photonics. In this work, we consider the near-field radiative heat transfer between two magnetic Weyl semimetal slabs and show that the heat transfer can be controlled with a relative rotation of the parallel slabs. Thanks to the intrinsic nonreciprocity of the surface modes, this so-called twisting method does not require surface structuring like periodic gratings. The twist-induced control of heat transfer is due to the mismatch of the surface modes from the two slabs with a relative rotation.

扭曲感应控制磁性Weyl半金属之间的近场热辐射

由于霍尔效应的异常大，在没有外部磁场的情况下，磁性Weyl半金属可以支持不可逆的表面等离子体激元极化子模式。这意味着磁性Weyl半金属可以在（热）光子学中找到新的应用。在这项工作中，我们考虑了两个磁性Weyl半金属板之间的近场辐射传热，并表明可以通过平行板的相对旋转来控制传热。由于表面模式固有的不可逆性，这种所谓的扭曲方法不需要像周期性光栅那样的表面结构。扭曲引起的传热控制是由于两个平板的表面模式相对旋转而导致的不匹配。
