磁热等离子体:从理论到应用

Magneto-thermoplasmonics: from theory to applications

Annika Ott, Riccardo Messina, Philippe Ben-Abdallah, Svend-Age Biehs

摘要:

本文综述了磁光多粒子系统中纳米尺度辐射传热的最新理论进展。我们详细讨论了循环热通量,巨磁阻效应,持续热流,和热霍尔效应的光在这样的系统中的波动电动力学的框架内,使用偶极近似。我们表明,在这样的系统中的热通量的方向性,原则上可以理解通过分析的竞争贡献的磁场依赖的偶极共振的热交换的量子数m = +1和m =-1。本文还简要讨论了这些效应在热传感和磁传感中的一些潜在应用。

英文摘要:

We review recent theoretical developments on the nanoscale radiative heat transfer in magneto-optical many-particle systems. We discuss in detail the circular heat flux, the giant magneto-resistance effect, the persistent heat current, and the thermal Hall effect for light in such systems within the framework of fluctuational electrodynamics, using the dipolar approximation. We show that the directionality of heat flux in such systems can in principle be understood by analyzing the competing contributions to the heat exchange of the magnetic-field-dependent dipolar resonances of quantum numbers m = +1 and m = -1. Some potential applications of these effects to thermal and magnetic sensing are also briefly discussed.
