Link between the photonic and electronic topological phases in artificial graphene
Sylvain Lannebère, Mário G. Silveirinha
In recent years the study of topological phases of matter has emerged as a very exciting field of research, both in photonics and in electronics. However, up to now the electronic…
Modal expansions in dispersive material systems with application to quantum optics and topological photonics
Mario G. Silveirinha
It is proven that in the lossless case the electrodynamics of a generic inhomogeneous possibly bianisotropic and nonreciprocal system may be described by an augmented state-vector…
Drift-induced Unidirectional Graphene Plasmons
Tiago A. Morgado, Mário G. Silveirinha
Nonreciprocal photonic devices enable "one-way" light flows and are essential building blocks of optical systems. Here, we investigate an alternative paradigm to break reciprocity…
Light tunneling anomaly in interlaced metallic wire meshes
Hafssaa Latioui, Mário G. Silveirinha
For long wavelengths three-dimensional connected metallic wire meshes are impenetrable by light and have an electromagnetic response similar to that of an electron gas below the pl…
Bistability in mushroom-type metamaterials
David E. Fernandes, Mário G. Silveirinha
Here, we study the electromagnetic response of asymmetric mushroom-type metamaterials loaded with nonlinear elements. It is shown that near a Fano resonance these structures may ha…
Negative Landau damping in bilayer graphene
Tiago A. Morgado, Mário G. Silveirinha
We theoretically demonstrate that a system formed by two coupled graphene sheets enables a negative damping regime wherein graphene plasmons are pumped by a DC current. This effect…
