Surface scalar plasmons on curved interfaces: a venue for analogue gravity
Matheus E. Pereira
We investigate whether the geometry of a curved conductor--dielectric interface can modify the effective mass and propagation of scalar surface plasmons (SSPs). In the hydrodynamic…

Perturbative aspects of analogue FLRW spacetime Jellium models
Matheus E. Pereira, Hermano Velten, Francisco B. Lustosa +1
We study electro-acoustic perturbative modes in homogeneous, isotropic and expanding -- dubbed as Friedmann-Lemaitre-Robertson-Walker (FLRW) -- Jellium models, thereby mimicking de…
