摘要:

纳米级物体之间的近场电磁相互作用产生增强的辐射热传递,其可以大大超过由远场黑体辐射建立的限制。在这里,我们提出了一个理论框架来描述的时间动力学的纳米结构,这是基于使用的本征模展开的方程,支配这个过程的合奏辐射传热。使用这种形式主义,我们确定的基本原则,确定的纳米结构的集合的热化,揭示一般,但往往不直观的动态。我们的研究结果提供了一个优雅的和精确的方法,有效地分析包含大量的纳米粒子的系统中的近场辐射传热的时间动态。

英文摘要:

The near-field electromagnetic interaction between nanoscale objects produces enhanced radiative heat transfer that can greatly surpass the limits established by far-field black-body radiation. Here, we present a theoretical framework to describe the temporal dynamics of the radiative heat transfer in ensembles of nanostructures, which is based on the use of an eigenmode expansion of the equations that govern this process. Using this formalism, we identify the fundamental principles that determine the thermalization of collections of nanostructures, revealing general but often unintuitive dynamics. Our results provide an elegant and precise approach to efficiently analyze the temporal dynamics of the near-field radiative heat transfer in systems containing a large number of nanoparticles.
