Bounds on Black Bounces from Phenomenological Imprints

Alana C. L. Santos, Marcos S. Melo, Roberto V. Maluf

In this work, we derive phenomenological constraints on a symmetric black-bounce geometry supported by an anisotropic fluid. We investigate the effects of the bounce parameter and…

Shadows and gravitational perturbations of black bounces

Alana C. L. Santos, Leandro A. Lessa, Roberto V. Maluf +1

We investigate axial gravitational perturbations and shadow formation in black-bounce geometries supported by anisotropic fluids within general relativity. Two distinct classes of…

Echoes and quasinormal modes of asymmetric black bounces

Alana C. L. Santos, Leandro A. Lessa, Roberto V. Maluf +1

We study quasinormal modes and echoes of symmetric and asymmetric black bounce solutions generated by anisotropic fluids within the framework of general relativity. We derive the e…

Yang-Mills Casimir wormholes in

Alana C. L. Santos, Célio R. Muniz, Roberto V. Maluf

This work presents new three-dimensional traversable wormhole solutions sourced by the Casimir density and pressures related to the quantum vacuum fluctuations in Yang-Mills (Y-M)…

Casimir Effect in a Schwarzschild-Like Wormhole Spacetime

A. C. L. Santos, C. R. Muniz, L. T. Oliveira

In this paper, we investigate the role of gravito-inertial effects on the Casimir energy of a massless scalar field confined between two parallel plates orbiting a static and zero…

Contributions of a Modified Electrodynamics to the Molecular Biochirality

Alana C. L. Santos, Celio R. Muniz, Leonardo T. Oliveira +1

In this paper, we investigate the physical basis behind the molecular biochirality from the computation of a parity violation energy difference (PVED) in enantiomers of organic mol…
