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…

The 2D Lorentz-violating fermionic Casimir effect under thermal conditions
K. E. L. de Farias, M. A. Anacleto, Iver Brevik +4
In the present work, we study a fermionic Lorentz invariance violation (LIV) theory with a CPT-even extension and analyze its impact on the Casimir effect under the MIT bag boundar…

Boundary effects in classical liquid density fluctuations at finite temperature
Herondy Mota, K. E. L. de Farias
We investigate thermal effects on density fluctuations in confined classical liquids using phonon quantization. The system is modeled via a massless scalar field between perfectly…
