A phenomenological description of critical slowing down at period-doubling bifurcations
Edson D. Leonel, João P. C. Ferreira, Diego F. M. Oliveira
We present a phenomenological description of the critical slowing down associated with period-doubling bifurcations in discrete dynamical systems. Starting from a local Taylor expa…
On a Sharp Fourier Extension Inequality on the Circle with Lacunary Spectrum
Felipe Gonçalves, João Paulo Ferreira
We prove a sharp Fourier extension inequality on the circle for the Tomas-Stein exponent for functions whose spectrum satisfies .
Generalized Neumann boundary condition for the scalar field
J. C. Fernandes, J. P. Ferreira, F. E. Barone +3
In this paper, we explore the Klein-Gordon field theory in dimensions in the presence of a -dimensional hyperplanar -like potential that couples quadratically to…
Considerations on electromagnetic radiation in Podolsky electrodynamics within a Lorentz-symmetry violating framework
J. P. Ferreira, Patricio Gaete, José Abdalla Helayël-Neto
We explore how higher-order derivative terms impact a physical observable within a Lorentz-Symmetry Violating (LSV) framework. We specifically examine Podolsky electrodynamics coup…
