摘要:

多体物理学旨在理解由许多相互作用的物体组成的系统的涌现特性。本文综述了近场区热辐射源相互作用多体系统辐射传热的研究进展。近场辐射传热是一个新兴的研究领域,其中发射器的合作行为产生了特殊的效果,可以利用这些效果来控制纳米尺度的热流。利用扩展的标准Polder和van Hove随机形式主义来处理$N$ -体系统中的热生场,以及它们通过多次散射的相互作用,导出了描述任意互易和非互易多端系统中热光子介导的热交换的广义Landauer类理论.在这篇评论中,我们使用这种形式主义来解决这些系统中的运输和动力学从统一的角度来看。我们的讨论包括:(i)热通量的非加性及其相关效应的描述,包括基本限制以及纳米结构和材料选择的作用,(ii)平衡态和多稳态的研究,(iii)弛豫动力学(热化)走向局部和全局平衡,(iv)在由大量物体组成的有序和无序系统中的热传输状态的分析,密度和范围的相互作用,和(v)热磁效应的磁光系统和非厄米多体系统中的热输运机制的描述。最后,我们列出了突出的挑战和有前途的未来研究方向的审查。

英文摘要:

Many-body physics aims to understand emergent properties of systems made of many interacting objects. This article reviews recent progress on the topic of radiative heat transfer in many-body systems consisting of thermal emitters interacting in the near-field regime. Near-field radiative heat transfer is a rapidly emerging field of research in which the cooperative behavior of emitters gives rise to peculiar effects which can be exploited to control heat flow at the nanoscale. Using an extension of the standard Polder and van Hove stochastic formalism to deal with thermally generated fields in $N$-body systems, along with their mutual interactions through multiple scattering, a generalized Landauer-like theory is derived to describe heat exchange mediated by thermal photons in arbitrary reciprocal and non-reciprocal multi-terminal systems. In this review, we use this formalism to address both transport and dynamics in these systems from a unified perspective. Our discussion covers: (i) the description of non-additivity of heat flux and its related effects, including fundamental limits as well as the role of nanostructuring and material choice, (ii) the study of equilibrium states and multistable states, (iii) the relaxation dynamics (thermalization) toward local and global equilibria, (iv) the analysis of heat transport regimes in ordered and disordered systems comprised of a large number of objects, density and range of interactions, and (v) the description of thermomagnetic effects in magneto-optical systems and heat transport mechanisms in non-Hermitian many-body systems. We conclude this review by listing outstanding challenges and promising future research directions.
