Estimating power-law exponents from observations in electromagnetic non-minimal Maxwell-Gauss-Bonnet coupling cosmology

RA El-Nabulsi, W Anukool - Journal of High Energy Astrophysics, 2024 - Elsevier
We discuss a generalized non-minimal Maxwell-Gauss-Bonnet power-law cosmological
model characterized by the presence of electromagnetic field and variable cosmological and …

Tachyon inflation in the holographic braneworld

N Bilić, DD Dimitrijević, GS Djordjevic… - … of Cosmology and …, 2019 - iopscience.iop.org
A model of tachyon inflation is proposed in the framework of holographic cosmology. The
model is based on a holographic braneworld scenario with a D3-brane located at the …

Flat and bent branes in Born–Infeld-like scalar field models

I Andrade, MA Marques, R Menezes - The European Physical Journal C, 2024 - Springer
In this work, we investigate the presence of thick branes modeled by a single scalar field
with Born–Infeld-like dynamics. We consider the 4-dimensional metric being Minkowski, de …

Tachyon scalar field in a braneworld cosmology

DD Dimitrijevic, N Bilić, GS Djordjevic… - … journal of modern …, 2018 - World Scientific
We analyze a tachyon cosmological model based on the dynamics of a 3-brane in the bulk
of the second Randall–Sundrum model. This model contains extended general warp …

Tachyon constant-roll inflation in Randall-Sundrum II cosmology

M Stojanovic, N Bilic, DD Dimitrijevic… - arXiv preprint arXiv …, 2023 - arxiv.org
We study inflation in a model with constant second slow-roll parameter $\eta $. In this case,
the Hubble expansion rate equation has analytical solutions describing four possible …

Particle creation and reheating in a braneworld inflationary scenario

N Bilić, S Domazet, GS Djordjevic - Physical Review D, 2017 - APS
We study the cosmological particle creation in the tachyon inflation based on the D-brane
dynamics in the Randall-Sundrum (RSII) model extended to include matter in the bulk. The …

A de Sitter tachyonic braneworld revisited

N Barbosa-Cendejas… - … of Cosmology and …, 2018 - iopscience.iop.org
Within the framework of braneworlds, several interesting physical effects can be described in
a wide range of energy scales, starting from high-energy physics to cosmology and low …

Holographic cosmology and tachyon inflation

N Bilić - International journal of modern physics A, 2018 - World Scientific
After a brief introduction to the AdS/CFT holography, a tachyon inflation will be discussed in
the framework of holographic cosmology. The model is based on a holographic braneworld …

Bianchi IX geometry and the Einstein–Maxwell theory

AM Ghezelbash - Classical and Quantum Gravity, 2022 - iopscience.iop.org
We construct numerical solutions to the higher-dimensional Einstein–Maxwell theory. The
solutions are based on embedding the four dimensional Bianchi type IX space in the theory …

Dynamical system analysis of Randall-Sundrum model with tachyon field on the brane

A Ravanpak, GF Fadakar - Physical Review D, 2020 - APS
In this article, we use the dynamical system approach to study the linear dynamics of a
Randall-Sundrum braneworld model with a tachyon scalar field confined to the brane. We …
