Inflationary magnetogenesis with reheating phase from higher curvature coupling
Kazuharu Bamba, E. Elizalde, S. D. Odintsov +1
We investigate the generation of magnetic fields from inflation, which occurs via breakdown of the conformal invariance of the electromagnetic (EM) field, when coupled with the Ric…
Growth of Perturbations using Lambert Equation of State
Manisha Banerjee, Sudipta Das, Abdulla Al Mamon +2
Recently, a novel equation of state (EoS) parameter for dark energy has been introduced which deals with a special mathematical function, known as the Lambert function. In this…
Stability Analysis of Charged Rotating Black Ring
Riasat Ali, Kazuharu Bamba, Muhammad Asgher +2
We study the electromagnetic field equation along with the WKB approximation. The boson tunneling phenomenon from charged rotating black ring(CRBR) is analyzed. It is examined that…
A Generalized Interacting Tsallis Holographic Dark Energy Model and its thermodynamic implications
Abdulla Al Mamon, Amir Hadi Ziaie, Kazuharu Bamba
The paper deals with a theoretical model for interacting Tsallis holographic dark energy (THDE) whose infrared (IR) cut-off scale is set by the Hubble length. The interaction b…
Measure of Complexity in Self-Gravitating Systems using Structure Scalars
Z. Yousaf, Kazuharu Bamba, M. Z. Bhatti +1
The aim of this paper is to present the definition of complexity for static self-gravitating anisotropic matter proposed in theory, where is the Gauss-Bonnet term and…
Neutral compact spherically symmetric stars in teleparallel gravity
G. G. L. Nashed, Amare Abebe, Kazuharu Bamba
We present novel neutral and uncharged solutions that describe the cluster of Einstein in the teleparallel equivalent of general relativity (TEGR). To this end, we use a tetrad fie…
The cosmological bulk flow in QCDM model: (In)consistency with
A. Salehi, M. Yarahmadi, S. Fathi
We study the bulk flow of the local universe using Type Ia supernova data by considering a class of cosmological model which is spatially flat,(FRW) space-times and contains cold d…
