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 on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-Domínguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
Tunable exciton polaritons in biased bilayer graphene
V. G. M. Duarte, P. Ninhos, C. Tserkezis +3
By harnessing the unique properties of bilayer graphene, we present a flexible platform for achieving electrically tunable exciton polaritons within a microcavity. Using a semiclas…
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…
Electrically Tunable Interband Collective Excitations in Biased Bilayer and Trilayer Graphene
Tomer Eini, M. F. C. Martins Quintela, J. C. G. Henriques +4
Collective excitations of charged particles under the influence of an electromagnetic field give rise to a rich variety of hybrid light-matter quasiparticles with unique properties…
Harnessing Ultraconfined Graphene Plasmons to Probe the Electrodynamics of Superconductors
A. T. Costa, P. A. D. Gonçalves, D. N. Basov +3
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultr…
