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…

Gravitational Dipole Moment in Braneworld Model
Eugênio Bastos Maciel, M. A. Anacleto, E. Passos
We investigate the gravitational effects on the relativistic Dirac theory of a system such as a Hydrogen atom in the braneworld scenario. A gravitational dipole moment like contrib…
