Near-Field Heat Transfer in Topological Systems
Topological plasmonic systems like a honeycomb lattice of plasmonic nanoparticles (see figure) are characterized by the fact that there is a phase transition between a topologically trivial and non-trivial phase when changing the geometrical parameters of the lattice. In the non-trivial phase, so-called edge states (and corner states) occur which are topologically protected and therefore robust with respect to perturbations. We investigate the influence of these topological edge states on the properties of the fluctuating near-field as well as the possibility to control the energy and heat transport in nanoparticle lattices by means of these topological edge states.
