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,…
Lorentz-violating modifications to particle dynamics, thermodynamics and vacuum energy in bumblebee gravity
A. A. Araújo Filho, K. E. L. de Farias, E. Passos +5
We investigate how spontaneous Lorentz symmetry breaking in bumblebee gravity modifies particle dynamics, thermodynamics, and vacuum energy around a static black hole background. S…
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…
