Thermal radiation and near-field thermal imaging of a plasmonic Su-Schrieffer-Heeger chain
arXiv:2209.02038 · doi:10.1063/5.0123515
Abstract
We investigate the direct thermal emission spectrum of a plasmonic Su-Schrieffer-Heeger chain of InSb nanoparticles as well as its far-field emission due to near-field scattering by a sharp tip as it is used in scattering type thermal microscopes. We discuss the measurability of the topological phase transition in such far-field and near-field experiments and highlight the signatures of the topological edge modes. We further discuss the impact of a substrate.
