论文摘要
我们探讨了两个铁磁绝缘子板在存在扭曲磁场的情况下具有强大的扭曲引起的近场辐射传热。利用波动电动力学的形式主义,我们发现在大阻尼条件下存在大型扭曲引起的热开关比率和非单调扭曲操作,以在小型阻尼状态下进行热传递,与非旋转诱导的扭曲诱导的效果相关,非旋转椭圆表面镁质棒极 - 表面表面表面镁质棒极 - 摩根元素和扭曲 - 扭转元素和扭曲 - 良好。此外,在超小的阻尼条件下,可以通过扭曲的非谐波表面 - 摩尼 - 摩尼龙杆的表面辐射传热来显着增强。这种扭曲诱导的效果适用于其他类型的各向异性板,并具有timereveral对称性的破坏。我们的发现提供了一种在纳米级热管理中扭曲和磁控制的方法,并通过Twistronics概念对其进行了改进。
We explore that two ferromagnetic insulator slabs host a strong twist-induced near-field radiative heat transfer in the presence of twisted magnetic fields. Using the formalism of fluctuational electrodynamics, we find the existence of large twist-induced thermal switch ratio in large damping condition and nonmonotonic twist manipulation for heat transfer in small damping condition, associated with the different twist-induced effects of nonreciprocal elliptic surface magnon-polaritons, hyperbolic surface magnon-polaritons, and twist-non-resonant surface magnon-polaritons. Moreover, the near-field radiative heat transfer can be significantly enhanced by the twist-non-resonant surface magnon-polaritons in the ultra-small damping condition. Such twist-induced effect is applicable for other kinds of anisotropic slabs with timereversal symmetry breaking. Our findings provide a way to twisted and magnetic control in nanoscale thermal management and improve it with twistronics concepts.
