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…
Tsallis holographic dark energy in the brane cosmology
S. Ghaffari, H. Moradpour, J. P. Morais Graça +2
We study some cosmological features of Tsallis holographic dark energy (THDE) in Cyclic, DGP and RS II braneworlds. In our setup, a flat FRW universe is considered filled by a pres…
Some exact results on quantum Newtonian cosmology
H. S. Vieira, V. B. Bezerra, C. R. Muniz +1
We obtain the wave functions associated to the quantum Newtonian universe with a cosmological constant which is described by the Schrödinger equation and discuss some aspects of it…
Resonant frequencies of a charged scalar field in the Garfinkle-Horowitz-Strominger dilaton black hole
H. S. Vieira, V. B. Bezerra, C. R. Muniz +1
We use the exact analytical solution of the radial part of the Klein-Gordon equation describing a charged massive scalar field in the electrically charged Garfinkle-Horowitz-Stromi…
Tsallis holographic dark energy in the Brans-Dicke cosmology
S. Ghaffari, H. Moradpour, I. P. Lobo +2
Using the Tsallis generalized entropy, holographic hypothesis and also considering the Hubble horizon as the IR cutoff, we build a holographic model for dark energy and study its c…
Electronic properties of single and double napped carbon nanocones
F. A. Gomes, V. B. Bezerra, J. R. F Lima +1
In this paper we study the electronic properties of carbon nanocones with one and two nappes, with pentagonal and heptagonal defects in their lattices. We use the continuum model,…
