Observational insights into the accelerating universe through reconstruction of the deceleration parameter

DM Naik, NS Kavya, V Venkatesha - Chinese Physics C, 2023 - iopscience.iop.org
Recent developments in the exploration of the universe suggest that it is in an accelerated
phase of expansion. Accordingly, our study aims to probe the current scenario of the …

Quasinormal modes of Gauss-Bonnet-AdS black holes: towards holographic description of finite coupling

RA Konoplya, A Zhidenko - Journal of High Energy Physics, 2017 - Springer
A bstract Here we shall show that there is no other instability for the Einstein-Gauss-Bonnet-
anti-de Sitter (AdS) black holes, than the eikonal one and consider the features of the …

Static topological black hole with a nonminimal derivative coupling and a nonlinear electromagnetic field of Born-Infeld type

MM Stetsko - Physical Review D, 2020 - APS
We consider scalar-tensor gravity with nonminimal derivative coupling and Born-Infeld
electromagnetic field which is minimally coupled to gravity. Since the cosmological constant …

Noncommutative effects of charged black hole on holographic superconductors

D Parai, D Ghorai, S Gangopadhyay - General Relativity and Gravitation, 2018 - Springer
In this paper, we analytically investigate the noncommutative effects of a charged black hole
on holographic superconductors in the probe limit. The effects of charge of the black hole is …

Meissner effect in holographic superconductors with Dirac–Born–Infeld electrodynamics

D Ghorai, S Gangopadhyay, R Banerjee - Modern Physics Letters A, 2020 - World Scientific
In this paper, we have investigated the Meissner effect of holographic superconductors in
the presence of Dirac–Born–Infeld electrodynamics. The matching method is applied to …
