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 ...

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 ...
