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…

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…
