Substrate-driven topological engineering in plasmonic Su-Schrieffer-Heeger chains
Florian Herz, Alireza Naeimi, Svend-Age Biehs
We demonstrate the possibility of engineering the topological band structure of a plasmonic Su-Schrieffer-Heeger (SSH) chain through the interaction with its electromagnetic enviro…
Thermal Casimir Force Imaging of Nonequilibrium Hot Electrons
Weikang Lu, Ziyi Xu, Hewan Zhang +11
The thermal Casimir effect, arising from fluctuating electromagnetic fields of thermally agitated charges, induces thermosensitive forces and presents a novel approach to detecting…
Feynman paradox induced by vacuum and thermal fluctuations
Svend-Age Biehs, Ivan Latella
A charged particle initially at rest in an external magnetic field starts to rotate when the magnetic field is switched off. This is a variant of the Feynman disc paradox, where th…
Transition from near-field to extreme near-field radiative heat transfer
Fridolin Geesmann, Philipp Thurau, Sophie Rodehutskors +4
The radiative heat transfer in the extreme near-field regime, i.e. for distances below 10 nm, remains poorly understood. There are competing experimental results in this regime, wi…
On persistent energy currents at equilibrium in non-reciprocal systems
Svend-Age Biehs, Ivan Latella
We investigate the properties of the mean Poynting vector in global thermal equilibrium, which can be non-zero in non-reciprocal electromagnetic systems. Using dyadic Green's funct…
Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-DomÃnguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
