Nanoscale heat radiation in non-reciprocal and topological many-body systems — •Svend-Age Biehs — Institut für Physik, Carl von Ossietzky Universität Oldenburg, Germany

I will start with a short introduction to the experimental and theoretical advances achieved in the rapidly evolving field of nanoscale heat radiation with a focus on the theoretical development of the many-body theory within the framework of fluctuational electrodynamics. Of particular interest are non-reciprocal systems giving rise to effects like the Hall effect for heat radiation and heat flux rectification by means of non-reciprocal surface waves. On the other hand, topological many-body systems offer the possibility to use edge modes for heat transport. I will discuss this heat flux channel in a topological Su-Schrieffer-Heeger chain and a honeycomb lattice of plasmonic nanoparticles.
