Generalized eigenvalue problem for an interface elliptic equation
Braulio B. V. Maia, Mónica Molina-Becerra, Cristian Morales-Rodrigo +1
In this paper we deal with an eigenvalue problem in an interface elliptic equation. We characterize the set of principal eigenvalues as a level set of a concave and regular functio…
Tunable THz Switch-Filter Based on Magneto-Plasmonic Graphene Nanodisk
Victor Dmitriev, Geraldo Melo, Wagner Castro
We propose and analyze a multifunctional THz device which can operate as a tunable switch and a filter. The device consists of a circular graphene nanodisk coupled to two nanoribbo…
Green's functions and method of images: an interdisciplinary topic usually cast aside in physics textbooks
Glauco Cohen Ferreira Pantoja, Walace S. Elias
In the present work we discuss how to address the solution of electrostatic problems, in professional cycle, using Green's functions and the Poisson's equation. By using this proce…
Graphene-Based Multifunctional Three-Port Far-Infrared Components
Victor Dmitriev, Geraldo Melo, Wagner Castro
Two graphene-based T-shaped multifunctional components for THz and Far-Infrared regions are proposed and analyzed. The first component can serve as a divider, a switch and a dynami…
Thermodynamics of bosonic systems in adS spacetime
Walace S. Elias, C. Molina, M. C. Baldiotti
We analyze the thermodynamics of massless bosonic systems in D-dimensional anti-de Sitter spacetime, considering scalar, electromagnetic, and gravitational fields. Their dynamics a…
Generalization of Regular Black Holes in General Relativity to Gravity
Manuel E. Rodrigues, Julio C. Fabris, Ednaldo L. B. Junior +1
In this paper, we determine regular black hole solutions using a very general theory, coupled to a non-linear electromagnetic field given by a Lagrangian …
