On the quasinormal modes in generalized Nariai spacetimes
Joás Venâncio
Quasinormal modes are eigenmodes of dissipative systems. For instance, if a spacetime with an event or cosmological horizon is perturbed from its equilibrium state, quasinormal mod…
Spin 2 Quasinormal Modes in Generalized Nariai Spacetimes
Carlos Batista, Joás Venâncio
In this work we analytically obtain the quasinormal spectrum for the gravitational perturbation on a higher-dimensional generalization of the Nariai spacetime that is comprised of…
Quasinormal Modes in Generalized Nariai Spacetimes
Carlos Batista, Joás Venâncio
The perturbations of fields with spin 0, 1/2, and 1 propagating in a higher-dimensional generalization of the charged Nariai spacetime are investigated. The boundary conditions lea…
Integrability of the Dirac Equation on Backgrounds that are the Direct Product of Bidimensional Spaces
Joás Venâncio, Carlos Batista
The field equation for a spin 1/2 massive charged particle propagating in spacetimes that are the direct product of 2-dimensional spaces is separated. Moreover, we use this result…
