Finite temperature Casimir effect for a spinor field in cosmic dispiration spacetime
Joás Venâncio, Herondy Mota, Azadeh Mohammadi
This study explores the finite temperature Casimir effect for a massive spinor field in cosmic dispiration spacetime, formed by the combination of a cosmic string and a screw dislo…
Thermal Casimir effect for a Dirac field on flat space with a nontrivial circular boundary condition
Joás Venâncio, Lameque Filho, Herondy Mota +1
This work investigates the thermal Casimir effect associated with a massive spinor field defined on a four-dimensional flat space with a circularly compactified spatial dimension w…
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…
Integrability of the Dirac Equation in the Presence of Fluxes on Product Manifolds
Joás Venâncio, Azadeh Mohammadi
This paper aims to show that the Dirac equation coupled to an arbitrary inhomogeneous flux field admits separation in manifolds formed from the direct product of bidimensional spac…
Two-Component Spinorial Formalism using Quaternions for Six-dimensional Spacetimes
Joás Venâncio, Carlos Batista
In this article we construct and discuss several aspects of the two-component spinorial formalism for six-dimensional spacetimes, in which chiral spinors are represented by objects…
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…
