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…
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…
Strongly Coupled Exciton--Hyperbolic-phonon-polariton Hybridized States in hBN-encapsulated Biased Bilayer Graphene
Tomer Eini, N. M. R. Peres, Yarden Mazor +1
Excitons in biased bilayer graphene are electrically tunable optical excitations residing in the mid-infrared (MIR) spectral range, where intrinsic optical transitions are typicall…
Nonlocal electrodynamics of two-dimensional anisotropic magneto-plasmons
A. J. Chaves, Line Jelver, D. R. da Costa +3
We present a hydrodynamic model, grounded in Madelung's formalism, to describe collective electronic motion in anisotropic materials. This model incorporates nonlocal contributions…
Roadmap for Photonics with 2D Materials
F. Javier GarcÃa de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Application of Madelung Hydrodynamics to Plasmonics and Nonlinear Optics in Two-Dimensional Materials
Simão S. Cardoso, A. J. Chaves, N. Asger Mortensen +1
This paper explores the application of Madelung hydrodynamic models to study two-dimensional electron gases, with a focus on nonlocal plasmonics and nonlinear optics. We begin by r…
