Quasinormal modes and shadow of Schwarzschild-Tangherlini black hole with GUP

J. A. V. Campos, M. A. Anacleto, F. A. Brito +2

In this work, we investigate quasinormal modes and the shadow of a Schwarzschild-Tangherlini black hole in dimensions, incorporating corrections arising from the Generalize…

Absorption and quasinormal modes by rotating acoustic black holes in Lorentz-violating background

J. A. V. Campos, M. A. Anacleto, F. A. Brito +2

In this work, we investigate the effects of Lorentz symmetry violation on the absorption cross section and quasinormal modes of a rotating acoustic black hole in (2+1) dimensions,…

Casimir Effect for a Massive Scalar Field in Lorentz-Violating Aether Compactification

K. E. L. de Farias, M. A. Anacleto, A. A. Araújo Filho +4

This work investigates the influence of Lorentz symmetry breaking, introduced by an aether-like field , on the Casimir effect within a five-dimensional flat spacetime. By cons…

Stefan-Boltzmann Law and Thermal Casimir Effect in Neutron Star Spacetime via Thermo Field Dynamics

K. E. L. de Farias, M. A. Anacleto, Rafael A. Batista +5

We investigate the thermal Casimir effect for a massless scalar field in the curved spacetime of a neutron star within the Thermo Field Dynamics (TFD) formalism. Starting from the…

Thin-shell gravastar model in a BTZ geometry with minimum length

M. A. Anacleto, A. T. N. Silva, L. Casarini

In this paper, we construct two spherically symmetric thin-shell gravastar models within a BTZ geometry with minimum length. Therefore, in the inner region of the gravastar, we con…
