Nonreciprocal thermal radiation of nanoparticles via spin-directional coupling with reciprocal surface modes
Jian Dong, Wenjie Zhang, Linhua Liu
Abstract
We demonstrate nonreciprocal far-field thermal emission and nonreciprocal near-field radiative heat transfer of Weyl semimetal nanoparticles when the circular thermal emission of the particles directionally couples with the spin of the surface modes supported by a reciprocal substrate. Our work can be applied to the development of nonreciprocal and directional thermal emitters and to the nanoscale routing of a radiative heat flux.
