Traversable Casimir Wormholes in D Dimensions
P. H. F. Oliveira, G. Alencar, I. C. Jardim +1
Wormholes (WH) require negative energy, and therefore an exotic matter source. Since Casimir energy is negative, it has been speculated as a good candidate to source that objects a…
Schwarzschild-like Wormholes in Asymptotically Safe Gravity
M. Nilton, G. Alencar
In this paper, we analyze the Schwarzschild-like wormhole in the Asymptotically Safe Gravity(ASG) scenario. The ASG corrections are implemented via renormalization group methods, w…
Ellis-Bronnikov Wormholes in Asymptotically Safe Gravity
G. Alencar, V. B. Bezerra, C. R. Muniz +1
In this paper, we investigate the simplest wormhole solution - the Ellis-Bronnikov one - in the context of the Asymptotically Safe Gravity (ASG) at the Planck scale. We work with t…
Gravitational bending angle with finite distances by Casimir wormholes
I. D. D. Carvalho, G. Alencar, C. R. Muniz
In this paper, we investigate the gravitational bending angle due to the Casimir wormholes, which consider the Casimir energy as the source. Furthermore, some of these Casimir worm…
Non-Integrability of Strings in Background and its 5D Holographic Duals
G. Alencar, M. O. Tahim
In this manuscript we study Liouvillian non-integrability of strings in background. We consider soliton strings and look for simple solutions in order…
Universal Mass Scale for Bosonic Fields in Multi-Brane Worlds
R. I. de Oliveira Junior, G. Alencar, R. R. Landim +1
In this paper we find an universal mass scale for all forms in multi-brane worlds model. It is a known fact the this model provides an ultralight mode for the fields. However,…
