论文摘要
在近场辐射传热（NFRHT）的背景下，多体效应的理论研究已经导致了许多热辐射现象的预测。已经特别注意非注册系统，其中缺乏洛伦兹互惠性会引起独特的物理效果。但是，在这方面的大多数理论工作都是借助考虑点状粒子或高度对称体（例如球体）的方法进行的，这些方法并不容易实现和探索实验。在这项工作中，我们基于热离散偶极近似（TDDA）开发了多体方法，该方法能够描述任意大小和形状的非偏置对象之间的NFRHT。我们说明了这种方法与两个相关现象的分析，即持续热电流的存在和光子热霍尔效应的潜力和相关性，即具有多个磁光体的系统。我们的多体TDDA方法为缩小实验和理论之间的差距铺平了道路，这阻碍了多体系统中NFRHT主题的进步。
The theoretical study of many-body effects in the context of near-field radiative heat transfer (NFRHT) has already led to the prediction of a plethora of thermal radiation phenomena. Special attention has been paid to nonreciprocal systems in which the lack of the Lorentz reciprocity has been shown to give rise to unique physical effects. However, most of the theoretical work in this regard has been carried out with the help of approaches that consider either point-like particles or highly symmetric bodies (such as spheres), which are not easy to realize and explore experimentally. In this work we develop a many-body approach based on the thermal discrete dipole approximation (TDDA) that is able to describe the NFRHT between nonreciprocal objects of arbitrary size and shape. We illustrate the potential and the relevance of this approach with the analysis of two related phenomena, namely the existence of persistent thermal currents and the photon thermal Hall effect, in a system with several magneto-optical bodies. Our many-body TDDA approach paves the way for closing the gap between experiment and theory that is hindering the progress of the topic of NFRHT in many-body systems.
