Dynamical Schwinger Production of Dipole--Antidipole Pairs in a Fractonic Lattice
Celio R. Muniz, R. N. Costa Filho
We investigate field-induced excitation production from the unit-filled Mott background of a one-dimensional dipole-conserving Bose--Hubbard chain driven by a periodic quadratic po…
Zero- and Finite-Temperature Casimir Effect in a Fracton Gauge Field
Celio R. Muniz
We investigate the zero- and finite-temperature Casimir interaction of the free trace-full scalar-charge fracton gauge field between two parallel reflecting boundaries. A variation…
Traversable Hyperbolic Wormholes with a Casimir-Memory Source: Complexity and Shell-Free Matching
Celio R. Muniz, Roberto Avalos, Jonathan A. Rebouças +2
Hyperbolically symmetric wormholes provide a setting in which negative energy densities arise from the throat geometry and finite matter configurations can be matched to the hyperb…
Fermionic Casimir memory from an anisotropic gravitational pulse
Celio R. Muniz, Herondy F. Santana Mota
We investigate the late-time energy deposited by a weak, spatially homogeneous anisotropic gravitational pulse in a massless Dirac field confined between two static parallel plates…
Electrically Charged Non-Abelian Black String in Anti-de Sitter Space
G. Alencar, R. N. Costa Filho, I. Jardim +1
We construct a new family of static, electrically charged, cylindrically symmetric black-string solutions of four-dimensional Einstein--Yang--Mills theory with a negative cosmologi…
Colored Black Holes in Logarithmic Nonlinear Yang--Mills Theory
Celio R. Muniz
We construct static, spherically symmetric, and asymptotically flat colored black holes in four-dimensional Einstein gravity coupled to a logarithmic nonlinear Yang--Mills field wi…
Junction Conditions, Radial Stability, Thermodynamics, Optical Geometry and Appearance of Polymer-Quintessence Thin-Shell Wormholes
Jonathan A. Rebouças, Edson Otoniel, M. C. Araújo +2
Thin-shell wormholes built from effective black hole geometries are sensitive not only to the lapse function but also to the choice of areal radius. We construct a reflection-symme…
Gravitational Lensing in a Kasner Background: Distinguishing Wormholes and Black Holes
Celio R. Muniz, Jonathan A. Rebouças, M. B. Cruz +1
We investigate gravitational lensing by compact objects embedded in anisotropic Bianchi-I cosmologies using directional Jacobi maps within the thin-lens approximation. The formalis…
Are Padé approximants suitable for modelling shape functions of traversable wormholes?
Jonathan Alves Rebouças, Celio Rodrigues Muniz
This study investigates the applicability of Padé approximants in constructing suitable shape functions for traversable wormholes, emphasizing their ability to satisfy essential ge…
Black holes as gravitational mirrors
L. C. N. Santos, F. M. da Silva, C. R. Muniz +1
Retrolensing is a gravitational lensing effect in which light emitted by a background source is deflected by a black hole and redirected toward the observer after undergoing nearly…
