Exceptional point induced by hyperbolicity in an electrostatic spherical shell
Álvaro Buendía, Marcelo S. Barreiro, Nuno M. R. Peres
Exceptional points (EPs) are non--Hermitian degeneracies at which both eigenvalues and eigenvectors coalesce, usually engineered through balanced gain and loss or non--reciprocity.…
Towards twisted, topological, and quantum graphene plasmonics
A. Octávio Soares, Nuno M. R. Peres
In this article, we analyze the quantum and topological properties of graphene-based plasmonic systems. We consider the following plasmonic materials: single-layer graphene, twiste…
Nanoscopy of surface polarization with oblique dipole orientations
V. G. M. Duarte, D. A. Miranda, D. F. P. Cunha +4
The boundary conditions imposed by confined dipoles with arbitrary orientation on surfaces are presented, extending the conventional in-plane (IP) and out-of-plane (OOP) treatments…
Screened topological plasmons in graphene plasmonic crystals
André Octávio Soares, Christos Tserkezis, N. M. R. Peres
We study topological effects in an one-dimensional plasmonic crystal formed by the screened plasmons emerging in a periodically modulated graphene sheet, placed on top of a metalli…
Tunable nonlinear excitonic optical response in biased bilayer graphene
M. F. C. Martins Quintela, N. M. R. Peres, T. Garm Pedersen
Biased bilayer graphene (BBG) is an important system for studies of excitonic effects in graphene--based systems, with its easily tunable bandgap. This bandgap is governed by an ex…
Topology in a one-dimensional plasmonic crystal
D. A. Miranda, Y. V. Bludov, N. Asger Mortensen +1
In this paper we study the topology of the bands of a plasmonic crystal composed of graphene and of a metallic grating. Firstly, we derive a Kronig-Penney type of equation for the…
