Gauge-covariant Raychaudhuri dynamics for spin-nondegenerate Lorentz-violating congruences
A. A. Araújo Filho, A. F. Santos, J. A. A. S. Reis +2
The paper derives a gauge‑covariant form of the Raychaudhuri equation for charged particle congruences with Lorentz‑violating dispersion relations, showing how electromagnetic fiel…
Perturbative dynamics and relativistic effects of a dyonic Kalb-Ramond black hole
A. A. Araújo Filho
We investigate perturbative dynamics, tidal effects, and relativistic frequency shifts in a dyonic Kalb-Ramond black hole generated by a Lorentz-violating antisymmetric tensor back…
Electromagnetic dynamics and geometric transport in spin-nondegenerate SME particles
A. A. Araújo Filho, A. F. Santos, J. A. A. S. Reis +2
We investigate the electromagnetic dynamics of spin-nondegenerate classical particle models arising from Lorentz-violating sectors of the Standard-Model Extension, focusing on the…
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 co…
Casimir phenomena in bumblebee gravity
D. S. Cabral, A. A. Araújo Filho, A. F. Santos
In this work, we analyze the Casimir effect associated with a massive, non-minimally coupled scalar field in static, spherically symmetric black hole spacetimes arising in bumblebe…
Entanglement, equivalence principle, and HBAR entropy, in a new bumblebee black hole
A. A. Araújo Filho, Wentao Liu
We investigate quantum information and thermodynamic properties of a new bumblebee black hole arising from spontaneous Lorentz symmetry breaking by analyzing near-horizon physics t…
