Distinguishing wormholes via Einstein rings and global curvature
M. B. Cruz, C. R. Muniz, R. M. P. Neves +1
In this work, we investigate the gravitational lensing properties of a static Ellis-Bronnikov wormhole embedded in a curved Friedmann-Lemaître-Robertson-Walker (FLRW) universe. By…

Traversable Casimir Wormholes with Gravitational Memory
Jonathan A. Rebouças, Francisco Bento Lustosa, Celio R. Muniz
We investigate a class of traversable wormhole geometries supported by an effective Casimir source corrected by gravitational memory. The construction is motivated by the fact that…

Traversable Wormholes Supported by Entropy-Inspired Effective Matter Sectors
Jonathan A. Rebouças, Francisco Bento Lustosa, Celio R. Muniz
The entropic interpretation of gravity suggests that spacetime geometry may encode thermodynamic information associated with microscopic degrees of freedom. In this context, the en…
