A recent paper in NPJ | Nanophotonics introduced a hybrid metal-dielectric non-Hermitian emitter (NHE) developed for thermophotovoltaic (TPV) systems. This emitter is designed to improve the ...
Here, the authors show that such an assumption of Hermiticity can be lifted in the context of a lattice model containing two non-Hermitian Dirac cones, with one hosting amplifying Dirac ...
