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…
Quasibound states of Schwarzschild acoustic black holes
H. S. Vieira, Kostas D. Kokkotas
In this paper, we study the recently proposed Schwarzschild acoustic black hole spacetime, in which we investigate some physical phenomena related to the effective geometry of this…
Class of solutions of the Wheeler-DeWitt equation with ordering parameter
H. S. Vieira, V. B. Bezerra, C. R. Muniz +2
In this letter, we discuss the Wheeler-DeWitt equation with an ordering parameter in the Friedmann-Robertson-Walker universe. The solutions when the universe was very small and at…
Scalar fields in a five-dimensional Lovelock black hole spacetime
H. S. Vieira
We study the interaction between massive scalar fields and the gravitational field produced by a higher dimensional Schwarzschild solution in a string cloud model. Exact analytical…
Resonant frequencies of a massless scalar field in the canonical acoustic black hole spacetime
H. S. Vieira, V. B. Bezerra
In this work we consider the exact solution of the Klein-Gordon equation describing a massless scalar field in the spacetime of a four dimensional canonical acoustic black hole, wh…
Charged scalar fields in a Kerr-Sen black hole: exact solutions, Hawking radiation, and resonant frequencies
H. S. Vieira, V. B. Bezerra
In this study, we consider charged massive scalar fields around a Kerr-Sen spacetime. The radial and angular parts of the covariant Klein-Gordon equation are solved in terms of the…
