论文摘要
由于较大的异常霍尔效应,磁性Weyl半法可以在没有外部磁场的情况下支持非邻次表面等离子体极化模式。这意味着磁性Weyl半法可以在(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半离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。由于表面模式的固有非交易性,这种所谓的扭曲方法不需要像周期性的光栅那样表面结构。扭曲引起的热传递控制是由于从两个平板的表面模式不匹配,并具有相对旋转。
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.
